The app didn't start correctly. Try refreshing your browser

Hello there


in a new created Sharepoint list (today) as well in one from the 19/2/20 (everything working fine at this date) the user is not able to open the Powerapps form (created from SP list) anymore. The error message is: "The app didn't start correctly. Try refreshing your browser." 

Session-ID: d3c101df-55f4-4095-9fd6-92b57bb747cd


The user who gets the error has site owner permission. I'm always able to open the form (as a creator and publisher of the form)

Please advice.


Best regards

Microsoft has answered this:


Turn on, at least temporarily, ad-hoc subscriptions. Run the following PowerShell command:
Set-MsolCompanySettings -AllowAdHocSubscriptions $true

Add to your tenant the required ad-hoc subscription to use a Power Apps per app plan by selecting the following link and completing the sign-up process:

You are now able to assign the Power Apps per app baseline access license to all users expected to use a Power Apps per app plan. Assigning the baseline access plan can be done in or

You can assign the Power Apps per app baseline access individually to users or assign the license to a security group that contains all users that will receive a Power Apps per app plan.

This step is optional, at this point the admin can turn off AllowAdHocSubscriptions for their tenant by using the following command:
Set-MsolCompanySettings -AllowAdHocSubscriptions $false


So it seems to have been a licensing problem that the form could not be opened any more. After three days of observation the solution seems to be stable. At the end we switched the ad-hoc subscriptions off again 🙂
