PowerApp fails to Submit to SharePoint

[lrarbin1977]

Hello All,

I have a customised Canvas PowerApp that submits data to a SharePoint List. This is available to everyone in our Office365 Tenant.

This works fine 99% of the time, but I'm getting the odd few users who don't seem to to be able the Submit the data. The App appears to have sent the data, there is no error message. But the data doesn't appear in the SharePoint list.

I'm not sure how to troubleshoot this as I'm not aware of any logs.

The only possible cause I can think of is that some of the effected users have had their email / UPN changed, either because they have switch companies (domain changed), errors in spelling their name when they were originally set up, marriage etc.
The app is in a 'Managed' environment (not the default). So the end user only has access to the App, not the Environment, I was wondering if this could be the cause?
Thanks
Laurence

Hello @lrarbin1977 

Can you check the security roles of this users on the sharepoint site and sharepoint list, I advise focus on the emails that have the UPN changed.

Hope this can help!

Hello pagonza,

I hadn't checked this as I was confused by the fact that 'nothing had changed'. It turned out it was a permissions issue with the list. We use AD groups to 'license' MS Teams, and these groups are used to allow access to this PowerApp. A while ago a 'new' group was created to do the same thing, some users have the 'old' group, some the 'new' group. The 'new' group was given access to the PowerApp, but not the underlying SharePoint List.
So that was the problem.
Thanks for the help.
