iPhone Authentication Loop



I have a user who, whenever he opens one of the apps shared to him, is taken to and required to sign-in. However, when he clicks "sign-in" on the web page it takes him back to that very same web page.


My troubleshooting steps so far

* Re-installed the app

* Closed all other apps on the iPhone

* Cleared Safari browser cache

* Re-shared the app in question to the user


Some background information

* The user is licensed for PowerApps

* The user is not using MFA and is a MS Exchange-only user (not synced from Windows AD)

* The user is using an iPhone 11


Thank you,

Hi @TYoungOR1 

It's possible that Safari is blocking third party cookies and this is blocking the authentication process from working correctly.

I would check the settings that are related to this area to see if it helps.

Figured out the problem. The user's trial of PowerApps needed to be renewed.
