My photos always start backing up EVERYTHING again at least once a week if the amount of new photos that has to back up is over 50 or something. The amount of times I've had to install and uninstall this app just to fix the bug is ridiculous. It's pretty much once a week I have to set up google photos all over again which takes at least about half an hour in general. I recommend something like one drive over Google photos, this app just won't function without all the bugs.
