I have been collecting pins on Apple Maps for years now. I had around 3,500 of them and back then to add a pin you needed to add it to a guide so I had a 'myPins' guide that was basically just my library. After Apple came out with 'Saved Places', I stopped adding pins to guides and just kept saved places as my library.
Fast forward to today, I finally decided to delete my old guide for some reason, and it appears that the guide was a parents and that deleted all of the pins inside, even from 'saved places'.
It was about 1,500 pins and honestly it is pretty upsetting. I realize that iCloud backup doesn't include Maps, and I've already tried to toggle Maps off in 'Saved to iCloud'. I wasn't in low power mode and I even saw the immediate change on my laptop too.
Is there anything I can do?!?! Any help is GREATLY APPRECIATED!
