There seems to be a user somewhere out there whom single-handedly killed the Google API quota. I am working with Google to work through this and adding some limits in the code to keep this from happening. Usage will reset tomorrow in the meantime.
Does this mean that things are not working correctly now? Currently only manual syncing works.
It is working fine now. You may have to sign out and restart for a fresh session. I am running tests on what will be 1.4.3 and plan to release it this week. I put some guards in place that should hopefully prevent this from happening. It’s been an eventful week, no pressure.
Thanks, logging out and in worked 
Glad to hear that! Hopefully, the one tester I am waiting for gives me the news I want to hear.
It just happened to me I am going to look into this more. I believe it is a Google issue. Can you verify what version you are on?
On version 1.3.1 (14)
It looks like an issue on Google’s side (again), I doubt their API has changed, but I am working on a solid fix. The only thing I have right now is to “Sign Out” and signed back in. No pressure.
Yes I did that again, but auto sync still doesn’t work.
Sorry for the late response. The latest build fixes the issue I am just waiting on Apple’s review.
