1- I’ve checked all views (moments/photos/memories)
2- yes, the photos from my photo app also show up on my iPhone and iCloud. (But what’s changed is that I used to have thousands of photos on my computer - and I know I only have the photos that are on my phone library on my computer library)
Basically, I’m wondering where the photos that were only on my computer (not my phone) go? There were thousands.
3- I’ve definitely deleted some photos - I didn’t realise that if you delete off your phone that it also deletes off your computer. But that still doesn’t explain where the photos that were never on my phone went...
