Hi, currently experiencing an issue in SharePoint for external users (guests). I have a customised PowerApps form built into a SharePoint list. Whenever a list item is selected the custom form would open normally for internal users. But for external users they would receive a "Sign in required" prompt. After clicking "sign in", the pop up will disappear and can continue as per normal. But would once again appear when selecting a different item or closing and reopening the same item. This issue only started occurring a couple months ago.
I had the external users test using various browsers and still the same issue persists. I'm wondering if there was a recent update which required external users (guests) to go through this process?
Note: They have no issue viewing the SharePoint list itself, just for the customised form.
Thanks
Hi @ANB, The external users all have user type guest and edit access. They are only required to use the form and not create.
Update: The issue has gotten worse, where the sign-in prompt would now keep appearing every few seconds after clicking sign in.
HI @GordenF , Just for the confirmation, Have you checked this?
