Hello remigijusb,
Since these issues seem to be related to having two Apple IDs, another option would be to migrate your data from one Apple ID to another. Of course, you cant migrate everything, like purchases, backups, etc, but if all of your purchases are related to one Apple ID, you can migrate most of your user-created data like photos, notes, contacts, etc, to that Apple ID.
When you sign out, any data stored in iCloud will be removed from your device but will remain in iCloud. Before you sign out, you’ll be asked if you want to keep a copy of any of this information on your device. You can learn more here:
Once signed out of the second Apple ID you can sign in with the Apple ID that has all of your purchases. This will merge the data on your devices with the data in iCloud. At that point, the issue should be resolved.
If that does resolve the issue, you can delete one of your Apple IDs. That said, if you delete an Apple ID, you cannot use the email address for another Apple ID. If that's the email address you want to use for your Apple ID (and it's not an iCloud email address), we recommend creating a new email address, changing the email address associated with your Apple ID to the new email address, and then deleting it. You can learn more here: How to delete your Apple ID account - Apple Support
Once you disassociate the email with the Apple ID to be deleted you can change the email address associated with the Apple ID that has all of the purchases: Change your Apple ID - Apple Support
Keep in mind, deleting an Apple ID is permanent. You can also try to migrate your data before changing or deleting your Apple ID to ensure you have everything you need.
Thanks.
