iPhone Authentication Loop

(0) ShareShare
ReportReport
Posted on by TYoungOR1 11

Hello,

 

I have a user who, whenever he opens one of the apps shared to him, is taken to apps.powerapps.com 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.

     

    Thanks,
