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.
