I had problems with my post a few weeks ago and posted about it on here. I didn't receive any post for 14 days and yet all around me my neighbours were receiving theirs, albeit sporadically. On the 15th day I actually got post and have had it steadily ever since, although last week went four days again without any. It comes at all different times of the day as well now, whereas before coronavirus, my post always came around midday. Coronavirus is causing the problem I'm afraid.
