Photos App / Finder Catalina
After installing Catalina Finder does not work properly when trying to sync to iPhone or iPad , using the Photos app photos does not sync from Mac to other devices , some photos are there and others are not. I have eventually managed to delete all photos from my iPhone and completely rebuilt my Photos Library from scratch I have tried all the suggested fixes and have also been in touch with Apple support and after all that have been informed that it might be a problem in Photos or Finder and to wait for an update.
In desperation I paid extra i cloud storage and uploaded all photos to the cloud and down to my iPad and iPhone and everything was as it should be , after doing that i then had over 7000 photos in my recent folder on both the mac and other devices , sorry to long winded but apple support told me that after 30 days the photos in recent would disappear but they are still there and if i try to delete it will delete on all devices so any help on the above would be great and is a fix coming out soon as it would appear this is a long standing problem.
