ive also had this problem ,,,one day i kept getting the alert from offerup a few minutes after i had already replyed to the message that was sent to me,,,,,,,,,,,,but the problem seemed to fix it self,was working fine the next day.
Lately messages have been 30 minutes late but the chaching sound either doesnt work at all or it makes the sound 10 minutes after the message has been sent, plus if im replying to messages and the buyer sends 1 back it doesnt appear in the line of current messages until i go back to the list of recrnt messages received and reopen that same message i was just replying to. So i never know if they reply till i go back and check. Its getting harder to make sales lately with sll these notificayion issuse constantly happening. At least the location issue has finally been fixed, plan on the notification issues being fixed in the next 3 months or so, that seems to be the time it takes to fix things.
Meanwhile thousands of buyers try the app and cant make a purchase because of it, close the app and uninstall it, then dpread the word about their experience. With so many problems trying to make a connection between buyers and sellers, the only buyers left here are all sellers looking for items posted for next to nothing since sellers cant make a sale and mark tgeur stuff down so cheap trying to sell anything. This hurts sellers bigtime, with no new buyers shopping here theres no money to be made at any price.
This app needs to be much more reliable and become way more buyer friendly, starting with the basics. Getting messages to work properly and getting the notifications to come through with the message is just the very least it should be able to do, without it the app is simply wasting everyones time.
