one of our customers gets a lot of pdf files via mail. He opens them in the e-mail app on his iPad and edits them. Unfortunately when he wants to save the file with his changes in owncloud, the file is saved but all changes are lost.
When you open the file in GoodNotes or send it via mail all changes are still there.
iOS version: iOS 12.3.1
ownCloud app version:
newest from app store
iPad Pro 12,9 2018
Do you have any ideas what is wrong?
Thanks a lot!
