Attempting to add or edit a basemap in ArcGIS Pro fails, returning the following error message:
Error: Failed to update basemap, selected basemap is not supported at this time.
The ArcGIS Online user subscription account is suspended due to insufficient credits in the account.
Note: The alternative workaround only adds or changes a basemap in an ArcGIS Pro session if the user is not signed in. A user must have sufficient ArcGIS Online credits for specific transactions, storage, and analytics across ArcGIS platforms. Refer to ArcGIS Online: Understand credits for more information.
