Hi@Kaiser,
Based on the issue that you mentioned, do you mean that your shared app link is wrong for it is a link pointed to the previous Sandbox environment.
Could you please share a bit more about the scenario, which environment do you operate in when you click the share button?
I have a test on my side and everything works fine.
In my scenario, I import my app as a package and create it as a new app into the Production environment. And then I toggle the environment to the Production and upload my package file.
Finally I share the app in the Production environment.
Please check your step to see if there is something wrong.
Hope it could help.
Best Regards,
Qi
