If a previous developer’s app [https://homey.app/en-nz/app/com.feibit/FeiBit/](https://homey.app/en-nz/app/com.feibit/FeiBit/) was rewritten to Sdk3,  
and the form of the previous app and store does not correspond in all respects to what is described here: [https://apps.developer.homey.app/app-store/guidelines](https://apps.developer.homey.app/app-store/guidelines)  
Is it absolutely necessary to change or can the original format remain?

In my experience, these things are typically checked when submitting a new app, not when updating an existing one.

You can always try to publish it and see what happens.

In my case, they have published app and asked me to update it to follow guidelines for the next time, which I did. But it always depends, what exactly hasn’t been followed.
