Gmail notifications stopped working on my Apple Watch Series 9

For anyone that might stumble across this and need help, I resolved the problem by uninstalling and reinstalling the Gmail app on my iPhone. It had somehow gotten glitchy with the phone which meant notifications couldn't go to my watch. After I reinstalled it, I reset my notifications and they started working on my phone again. Then tweaked some more settings on the watch app and now notifications also go to my watch.

Update (is anyone reading this?):

I finally just did a full reset of my watch and started it as new. I set everything up as it should be and received maybe two email notifications (from the Mail app, not Gmail) and not from my primary inbox (which is what I wanted -- not junk promotions and updates). Now I see I'm getting a couple Mail notifications in my watch's notification center, even though I have it OFF. It shouldn't be sending notifications there at all.

My watch's sound is off (by choice) but I do get haptics for phone calls and other apps. Just not mail. Apple's Mail seems really screwed up since the upgrade.

Thank you so much. I'm glad you got it working for you! Unfortunately, I didn't get it to work for me. I did have "Primary Only" selected so I changed that to "All Mail" -- I wasn't notified when I sent myself a couple of test emails.

When it worked, the haptic would buzz my watch and I'd see a new Gmail on the screen. (Not the mail app icon, but it said Gmail.) Then that just quit working entirely.

I made sure I have notifications on in the Gmail app on the phone and then went into the watch app and made sure that mirror my iPhone is on. It already was, but I toggled it off and back on anyway.

It's possible that it's an issue with the Gmail app, but it's also quite possible it's on Apple's side. Or possibly both. And Apple and Google aren't exactly friends so... :(

I can't imagine there is a setting I still have set wrong at this point. I feel like I have checked every setting there is on the iPhone's settings, Gmail app's settings, Apple Watch settings (on the phone and the watch itself). Maybe it really is some sort of OS glitch.

Question for you: on your watch, do you get the Gmail notification, or is it an Apple Mail notification that's connected to your Gmail account?

I forgot to mention that I did un-pair and re-pair my watch, too. That did not fix it.

It's like the Gmail app isn't talking to the Apple watch. Because I have it set to show in notification center, too, and nothing goes to the notification center on my watch.
