Hello Experts,

From last few days we are facing following error in every business central SaaS tenant  while upload updated extension app file. (Manual file upload in Sandbox Or Production)

Any new extension upload successfully in first time but if we make any changes try upload it again after increasing version. We get this error.

Deployment failed. Errors: App ID : 2670d5e7-d6d4-46b0-bcac-4beae9eed664 Message : { Cannot install the extension ALProject10_201219 by Default publisher_201219 1.0.1.0 because the tenant msft1a6720t44369542 already uses a different version of it. } - Job Id : 8c646bd9-4d04-4f5e-933e-8f0a8bbee621

    Dear Mohana,

    Thank you for solution.

    It was very strange behavior by Business Central Updated Version

    After un-install old extension system allow to install new extension.

    Previously we can able install new extension without un-install old version
