Sorry, hope this doesn’t confuse the thread. I can start a new one if so.
I tested it a bit more… discovered it works if I go directly to the site at baserow.site but not if I embed the site into my own website (I’m using Google Sites), which was working fine before, but that is what has changed. So it could be related to the embed, which may be a similar problem to this bug I reported, but that was 7 days ago, so… maybe unrelated. 
Sorry I didn’t think to check this. So its not the same issue as luckyhmm.
