Hi Vesa!
I have already submitted the issue: https://github.com/SharePoint/sp-dev-docs/issues/1409. Of course, we tried first to open a support ticket but support team told us that they didn't provide support to any issue related to third party development :-(. That's the reason I have decided to post here the problem and also at other channels

We've run into the same issue in the last two months. Over each tenant we provide PH solutions in (8 so far), we see that renewed client secrets do not work with the invalid issuer error. We ran into a wall with support, so we figured we would wait until others started reporting this. Well, here we are :)
As a workaround we use Remove-MSOLServicePrincipal (https://docs.microsoft.com/en-us/powershell/module/msonline/remove-msolserviceprincipal) to remove the registration and recreate it using the same Client ID on AppRegNew.aspx . When using the same client ID the granted permissions carry over. This gives a service interruption of half an hour to a couple of hours, but it's better then nothing.
