Hi @Наталия5E7C 

Hope you are doing well.

Sorry for the delayed response. As you have mentioned that Reader mobile does not allow you to edit. Would you mind sharing few more details to understand the issue better?

1. Is it with a particular file or with all files?

2. If possible, could you share the file with us?

3. What is the OS (Android/iOS)?

Hers is a help document you can refer to know more about edit PDF in Reader mobile: https://www.adobe.com/devnet-docs/acrobat/android/en/managingsubscriptions.html#open-edit-mode

Let us know if you need any more information 

Thanks,

Harsh
