How to make the old version of the application be deleted after updating in the app store?

Question

iOS

Hello.
Updated the old application (gallery for the museum), now all users who had the old version get a mountain of errors from the old version after the update. Reinstalling helps.
Also, if the application is installed for the first time, then everything is fine and there are no problems.
We think that these are the traces of the old application, but is it possible to somehow remove its traces during the update?

Answer 1

The AppStore has nothing to do with it, this is a jamb of programmers, they did not take into account that there were data from the old version, at least they could be deleted.

Answer 2

Definitely a cant in resources, something has changed in the stored data, and they are left from the old application. To avoid this, you need to do migrations that will bring the old data to the current form.
