Bug description

We have an issue using an iPad with Nextcloud, which is once we open any PDF files from Nextcloud or from an email application using an iPad and editing PDF files using Adobe Acrobat Pro, there will be an issue with synchronization once the file is uploaded to Nextcloud either it will not take the edit at all and sometimes the edit will not be taken completely, which means if we have edited 10 pages the reflection on Nextcloud would be only in 4 or maybe 6 pages.

Note that this issue is not continuous which means it happens very often and it it really slowing down our workflow . Your support is much appreciated

No source file, test, or diagnostic data is identified. Start by reproducing the iPad/iOS workflow with Adobe Acrobat and inspect the Nextcloud iOS synchronization behavior and available logs; done means edited PDF pages consistently reach Nextcloud without missing changes.
