Ok, I have received a reply already but I cannot reply to it so this issue is getting gradually more annoying.
I've purchased items in the last week, I've tried to leave feedback but get a message saying that I've not purchased anything in the last 60 days which I obviously have.
I've tried using the eBay app, eBay on my mobile browser and eBay on my desktop PC.
As already stated, I did receive a reply earlier today, but there are no boxes or links to click on to leave a reply. Only accept answer or leave kudos.
I'm getting regular emails telling me what's trending and what I'm watching so that's working.
