Not having tracking updates through app, email, or inpost

I'm having a few wee issues with vinted not showing tracking updates on the chats for when parcels are delivered. I've also failed to receive emails or messages (whether it be going to inpost lockers or to my address) or even on the inpost app. Never had an issue until a couple of weeks ago.

I'm going to try un-install and re-install the app and change my email in hope that will help.

I honestly feel so guilty for the sellers and reached out to some to explain. I don't know how it works from the sellers end, so I'm scared they'll lose out on postage money and feel guilter even thinking of that possibility tbh.

I've just raised an issue with vinted but wondering if others have had similar issues and what they did to fix it?
