i canot install teams app via playstore (warning this app cant be instaled) and when i try to upload apk same thing

What did you do to make it not download or install as it is more likely than not is user induced problem? Did you download/install it from different source? How many profiles you have? Permissions? Did you try removing it first?

It's the same as posting: why cant I breath whiteout providing any details - are you under water? Is your mouth open? are you alive?

My point is - please provide pertaining details in order to solicit helpful replies from knowledgeable and willing to help people instead of BS replies from assholes like me

Microsoft Teams can be installed from Google Play Store on this Pixel 7 device.

Are you signed into Google Play Store?

Did you grant all three apps (Google Play Store, Google Play Services and Google Services Framework) the network permission?

Please remember to be respectful and kind to others in this community. Sometimes it's better to give no answer and take a step away, and let somebody else help out instead.

It is worth your time persevering as Teams app works for me.
