I know it’s not my phone because I use WiFi at work but still I’m not able to see notifications. It says try again later. Meanwhile, those I’ve been communicating with think I’m ignoring them. I submitted a ticket in the help section but so far nothing.
I always recommend updating the app and clearing any cache/cookies for each device and browser you use to connect to OfferUp on. This will give your app a little refresh and typically resolves most error messages.,
You can troubleshoot yourself by signing out (clearing app cache / data) and then try to sign back in.
If the issue persists, you can ask if the servers are down for maintenance — at the OfferUp Twitter or you can contact customer care from the link below,
