Hi Josh,
Thanks for contacting us,
I understand that your Teams UI looks different from others and you only have three icons. There are a few possible reasons for this, and some ways to fix it.
One reason could be that you are using a different version of Teams than others. Teams has different versions for different platforms, such as desktop, web, mobile, and Linux. Each version may have slightly different features and UI elements. You can check which version of Teams you are using by clicking on your profile picture in the top right corner, then selecting About > Version. You can also update your Teams app to the latest version by clicking on Check for updates.
Another reason could be that you are using Teams for free, which has some limitations compared to the paid version of Teams. Teams for free only allows you to create or join teams with up to 300 members, and only gives you access to three apps: Chat, Calendar, and Files. You can see if you are using Teams for free by clicking on your profile picture in the top right corner, then selecting Manage account. You can upgrade to a paid version of Teams by clicking on Upgrade now.
A third reason could be that you have customized your Teams settings or preferences, which may affect how your Teams UI looks. You can change your settings by clicking on your profile picture in the top right corner, then selecting Settings. You can also customize your meeting view by clicking on the ellipsis (...) button in the meeting toolbar, then selecting Meeting options.
I hope this helps!
Regards, Sola
