After republishing the portal (no changes to the UI, just adding an authentication mechanism), the UI changed drastically.
Now when using Try this operation (previously Try it), the example dropdown only shows checkboxes. When clicking on one of them, the entire dialog closes and much of the text disappears.
See the screenshot below.

Could you please check suggested steps and let us know with an update.
- Clear Your Browser Cache: Sometimes, a simple cache clear can help with UI issues. Try clearing your browser cache or try accessing the portal from a different browser.
- Disable Extensions: If you have any browser extensions, especially ad-blockers or privacy-focused addons, try disabling those. They can sometimes interfere with the portal's scripts.
- Republish the Portal: If you’ve made any changes prior to the issues, make sure to republish the portal again to see if that resolves anything.
- Check for Errors: Open your browser’s developer tools (usually F12) and check the console for any errors when the UI crashes. This could provide insight into what's going wrong.
- Refer to Documentation: Double-check the Portal Management app documentation for any specific troubleshooting tips that might be relevant: Portal Management app overview
- Test in Incognito Mode: Sometimes issues can be caused by cookies or cached data. Try using the portal in an incognito or private browsing window.
If these suggestions don’t resolve your issue, could you provide a bit more information? Here are some follow-up questions that might help:
- What browser and version are you using? Have you tried different browsers?
- Are there any specific errors appearing in your console when the issue occurs?
- Did you notice any patterns when the UI crashes, such as specific examples or actions that trigger this behavior?
- How long has this issue been occurring since republishing the portal?

2025-08-27T10:02:41.5+00:00 Thank you, @Praveen Kumar Gudipudi .
I tried most of it before, but just in case, I tried it again. Cleared the cache, removed the cookies. Then republished the portal. Tried in incognito, all the same.
Tried it on 3 different browsers, they all have the same consistent issues after the last update. The browsers I tried are:
Chrome
Edge
VivadiDid you notice any patterns when the UI crashes, such as specific examples or actions that trigger this behavior?
Eh... Yes, I click like I say I did on any example, and that action causes the crash? What else would you like to know?
What I noticed is that in the API definitions in the designer, I no longer see the example descriptions. It's as if the values were deleted after the upgrade.
How long has this issue been occurring since republishing the portal?
Literally as soon as I republished the portal. And it has other UI issues you can see on the screenshot: the tags are out of bounds.
The crash trace is not very helpful, I'm afraid. But it looks like a null reference. It is:
theme.js:2 Click processed
theme.js:2 TypeError: Cannot read properties of undefined (reading 'typeName')

2025-08-27T10:09:59.34+00:00 Hello Vadim Berman,
Could you please confirm if this is related to an Azure APIM service issue?

Could you refer steps used for publishing the solution.
Also, please share the documentation of Azure Services used here.
Thank you for your inputs.

2025-08-27T11:42:22.5766667+00:00 @Praveen Kumar Gudipudi , sorry, I don't understand the question. Are you asking me whether after 8 years of relying on APIM I am sure it's APIM? You have the links and the screenshots, what is your professional opinion - does that not look like APIM?

2025-08-27T11:43:59.1266667+00:00 @Manas Mohanty You just click on Publish portal, same as always. Both from the designer and the Azure portal yield the same result.
And no need to act surprised, it's not like it's the first time APIM updates broke something.

2025-08-27T11:46:07.63+00:00 Guys, if it's the first time you hear about APIM and you use Copilot to respond, may I have a real human subject matter expert please? Since I'm paying for it.

I am from Azure AI/MLside. Sorry for less knowledge on API Management (Very costly solution to test on daily basis as per my past experience).
Was Just trying to confirm whether it is using any Azure AI services not as it mentioned NLP/NLU. We have text analytic service in Azure AI side, but the UI and endpoint look very different.
Handing over to respective personnel for further investigation.
Apology for the trouble caused because of my lesser knowledge and experience on APIM.

The issue is happening when Try new UI in the portal is set to true. When I disabled it, things have gotten back to normal.
Azure developers, please fix it.
