Error message for CEP extension: Compatible app required

Hi, user report that they can’t install my CEP extension.
The extension has InDesign 18 as minimum.

The error message says that v21.5 is required.

Is this a bug or why is this happening?
Can this be resolved somehow?

Any help appreciated!
Thanks!

After going back and forth with engineering a bit… do you see this error in the Creative Cloud desktop app if InDesign 21.3 is not installed first?

I’m also told to please run the Log Collector and share the logs (not in this forum): https://helpx.adobe.com/creative-cloud/apps/troubleshoot/diagnostics-repair-tools/run-log-collector-tool.html

I responded in the Adobe Slack in the Developer Champion channel as well, where Champions get to chat with engineers more directly.

It is most likely this same Adobe error where they cannot correctly identify the app is available if the language is not english
