Okay so that's my GDPR rant out of the way. I'll let you know later how that one turns out, they only have a bot social account and they only do paid support, so waiting 24 hour turn around on the tech guys, so far I am almost able to log in.
BUT I promised good news.
So here it is - I was staring at my Amazon "HD" tablet, it's a 7 gen or something, but the colours amazon used when they ported the stock calendar app are clearly not useable - but I thought this was the google app, but it's not. Sooo , see the screenie below that, where I get to eat my hat. I had to simply install the real google app, and now I am no longer blind.
