Google Photos does not automatically update/refresh new content

I have mounted a Google Photos drive and after the start of the drive the photos and albums are synched fine. But when I add Photos and/or Albums to Google Photos, they never appear automatically in my RaiDrive. I have to restart the “RaiDrive Filesystem Service” (or restart my PC).
Is this expected behaviour?

I am using RaiDrive version 2020.6.36


Additional finding:
When I look in the Y:\Photos#View All Photos (Slow) folder, the new photos are not there either.
But in the Y:\Photos#Recent Photos (Slow) folder new photos show up!
In the Y:\Albums folder they do also not appear at all.
