Deletion of synchronised pictures (from MacBook to Iphone) all in once on Iphone
Good Morning,
I have the following issue. I got an used MacBook, which still contained pictures from someone else (within the photo folder). By singing in with my AppleID all of those pictures were automatically (without notice) synchronized with my IPhone. Hence, all of these pictures are now on my phone (randomly over the years). I don't want to have them on my phone tho since they are from a different person and take a lot of storage(14.000 pictures, 2000 videos). I tried to delete these pictures on the MacBook and hoped it would synch with the IPhone, but the pictures are still there.
Does anyone know how to delete those picture all in ones from my phone without the need of going through all of them step by step?
Already looking forward to your answers!!
