Photos/iMovie Sync issues
I'm having problems with iMovie syncing with Photos so I can import videos that I've taken from my phone. Here is what I'm doing. I have taken some videos on my iPhone X. I then add those videos to an Album. I wait for a few hours to ensure that they sync. I'm at home connected to my normally fast internet connection so I have a solid signal. I then open up my MacBook and access Photos to ensure that I can see the Album and the videos therein. They are there. I then open up iMovie and it sees the Album but not all the videos and pictures inside. Some of the videos and pictures I've added have shown up but others don't. I waited another day and more pictures showed up but not all the videos. I double checked in Photos on my MacBook and they show there and can be played.
Any suggestions on how I can either get iMovie to sync properly with Photos (the preferred method) or do I need to export the videos and pictures one by one and then manually import them into iMovie?
MacBook Pro, iOS 11.4
