iCloud photos not showing up after changing system library
I recently copied my Photos library to an external drive and followed the steps to set it as the System Library. iCloud photos is turned on, and I have it set to download originals to this Mac. All my albums show up in the sidebar, but most of them are missing large chunks of photos.
I have tried turning iCloud on and off, changing the settings from download originals to optimize storage, nothing appears to make a difference. I cannot find any way to force this library to resync with iCloud and download all the missing files.
The photos are still showing up in iCloud on my phone, so nothing has been deleted. I've searched online and here in the forums and haven't been able to find a solution. Has anyone else dealt with this before or can someone point me in the right direction?
