Improve Google Calendar Instant Sync warning notification

Seems this app again gone off for some project. Sadly receiving such notification is not much helpful for me:

I have around 10 projects linked to this project (and some to separate ones), so now I don't know if it's just certain project out of sync or should I reclick all (which would be annoying). Putting project name or access id would be helpful.

I guess it might be related to recent API changes on their side, but even after regranting access without revoking it earlier, my authorization dates are still old, so no clue which one should I do.

Also clicking to notification just shows me that calendar already exists, but I got this notification like 4 times within 2 days now.
