Which is extra annoying because if you have Azure AD (I guess it’s Entra ID now) syncing from an on prem AD forest, half of the mailbox management shit in Exchange Online just doesn’t work and forces you to make the changes on-prem anyway.
This is about all app makers, not just ones in the Google Play Store. This also applies to third party app devs and hobbiests making open source apps to put up on alternative app stores like the all open source F-Droid.
