I haven't been receiving guest messages (anything from @guest.airbnb.com) to my Gmail inbox since September. I used to receive all of those messages just fine. I currently receive all other Airbnb messages - booking confirmations, support messages, etc.
I have triple-checked all of my notification settings in Airbnb. I have checked all spam filters, etc. in Gmail and have followed all troubleshooting guides on the issue. No luck!
Back in September I also stopped receiving ALL emails from Gmail because they started charging and I hadn't paid yet. After paying, I got all emails - but have never received any Airbnb guest messages since then. I'm not sure if that is a coincidence or not.
Is anyone in the same boat? I'm going crazy trying to figure this out and thinking about just changing my email address on my Airbnb account - but I really don't want to have to resort to that.
