Change Teams App Domain
I have a multi tenant app available in the Teams App store. I have to change the domain for that app due to Azure CDN Standard from Microsoft (classic) being retired. Instead of a ".azureedge.net" domain I'd like to use my own subdomain going forward.
To prevent service disruptions I would like to host the app frontend on two domains simultaniously and then change the domain in a manifest update.
However, it seems the App Registration Resource (Application ID URI) needs to contain the domain name for Teams to allow access to the app, otherwise I get the following error message:
Get SSO token failed with error: App resource defined in manifest and iframe origin do not match
Creating a new app registration would mean every customer would need to grant access again to my app registration.
What is the recommended approach to changing domains for a Teams app?

Yes, the domain in the Application ID URI must match what's in Teams.
Host both domains, keep the old URI until you update the manifest, then switch the URI.

@ThomasPe - You must update the Application ID URI and manifest, and customers will need to re-consent. There is no way to avoid re-consent when changing the domain in a multi-tenant Teams app. Host both domains during the transition to minimize disruption.

thanks for clarifying.
do I need to expect any issues when swtichig the teams app to a different app registration? I'm currently having issues in debug authenticating against the new app with my updated manifest, just want to make sure customers are not experiencing similar issues.
