Also a problem since the update - I posted this - but don't think it went into the right place no replies....I am unable to find it...
Prior to the 17 series of OS updates, all worked well. After that, the visualization of my "Apple Pencil modified pdf files" were (music lead sheets) very different when viewed on my iMac and older iPads (with older OS). That is, when I simultaneously look at the same pdf file from my iCloud on the different devices, the iPad Pro is totally different i.e., the identical file is viewed differently on the iPad Pro. This happens with ALL the modified pdf files when using the iPad Pro. I have spoken to 2 "senior" reps on the phone and taken 3 of my devices to the Apple Store to show them the problem. They all admit there is a problem. The immediate solution would be to install the old OS (prior to 17.0 OS) but, they say they are NOT able to to do that with an iPad. So, my expensive iPad is useless to me until Apple decides to fix the problem, which may be never. What can I do? All musicians now use the large format iPad for music files - which is OK if they are not altered.
