Getting "WebApplicationInfoIdConflictOnSideloadingIntoTeam" when trying to update a custom app
Hi, I'm trying to update the custom app that's already been published to the Teams store, I personally can't sideload it into my tenant, because I'm getting this error:
`WebApplicationInfoIdConflictOnSideloadingIntoTeam`
on this POST:
`https://teams.microsoft.com/api/apps/emea/beta/users/apps/definitions/appPackage`
The error has also been flagged by the Teams submission team, since they can't upload the newer version to the same tenant, hence they're not able to test it.
I've tried deleting all the other test applications from Teams Admin as well as Teams itself, with no luck.
I've been dealing with the issue for over a month now.
Is there a way to publish a newer version of the app for testing purposes, would I have to duplicate it?

braneg - Thank you for your inquiry about your Teams app development issue!
The WebApplicationInfoIdConflictOnSideloadingIntoTeam error usually happens when the webApplicationInfo.id of the custom app you're attempting to sideload conflicts with an existing app in the team.
Could you please verify that the webApplicationInfo.id in your app manifest is unique and not already in use by another app in the tenant?Shouldn't it be the same as the published app that I'm trying to update the version of?

braneg - If the ID is unique and you are still encountering issues, you should review and update the webApplicationInfo section in your manifest to ensure it is correctly configured. Additionally, since you've already tried deleting other test applications, double-check that there are no remaining instances of the app in the Teams Admin Center or within Teams itself, as remnants of the app can sometimes cause conflicts.
Please let us know if the issue still persists.
