We use Google Pub/Sub service for being notified when our users receive emails on their Gmail accounts.

We use the Ruby Gmail client (

https://googleapis.dev/ruby/google-api-client/latest/Google/Apis/GmailV1/GmailService.html) for watching the Gmail accounts of our user (connected with OAuth authorisation). We expose an endpoint in our Rails app for getting the posted notifications from Google.

It has worked for years without any problem for more than 1000 Gmail accounts. Since two weeks ago, we stopped receiving notifications for some accounts (I would say around 20). Each account is re-watched once a day (with stop_user() and then watch_user()), so it's not a problem of expired subscription.

Once a notification is not received for an account when there is a new mail, we never receive a notification anymore until it's re-watched. Then, it works for several minutes/hours and then it's broken again. It always happens for the same accounts.

The quotas page on GCP shows that there is not quotas limit exceeded.

I don't know if it's directly related to the Pub/Sub service or if it's a Gmail service issue...

I posted a question about that on StackOverflow (

https://stackoverflow.com/questions/70031798/notification-not-received-for-some-gmail-watched-accounts) and devs told me that it seems to be a bug.

Hello,

Thank you for reporting this behavior.

I am trying to reproduce it and will come back to you as soon as possible.

Regards.

It will it will be quite complicated to reproduce it since it seems to happen only for around 20 Gmail account on more than 1000.
I keep my fingers crossed that you can reproduce it !

I noticed during this weekend that when we refresh the subscription each night (stop_user() then watch_user()), we directly receive a notification for the account (when there are new emails). So we trigger a polling of the new emails and we get them (1, 10, 20, 80 new emails, it depends).

Once we receive this notification after refreshing the subscription for the problematic Gmail accounts, it's broken again until the next refresh of the subscription on the next night.

It seems to be fixed since we received notifications for the problematic Gmail accounts during the two past days. We didn't changed anything from our side during the weekend.
Maybe something has been fixed in Gmail service, I don't know.

So, I think we can close the issue.

Hello. It feels that this issue poppup again. Anyone else who is experiencing the same?

We're refreshing subscriptions every night, but for some users subscriptions stop at random moments until resubscribed again.

Yes, I am also having a similar issue where some subscriptions stop at random moments until they are resubscribed again. The only workaround I have found is scheduling the resubscriptions for all users more frequently, which isn't ideal.
