Could you please specify how was the app set up and how exactly is the site url entered in the multisite management?
I used the Sitefinity Project Manager for 12.2 and created a new Site called "Test"
I downloaded my Sitefinity 12.2 license from my account and during setup of the site I uploaded the lic filewhen requested during the setup.
As soon as the Dashboard showed up, the error above was displayed
Would you like me to record a video of the steps?
Here you go
Thanks! We'll check it.
We managed to reproduce it and it's a false positive alert. It will be fixed.
Thanks a million
Thank you for reporting it!
The fix will be shipped with the next patch.
