Managed to find a way to a chat window through Chrome and got some support.  The usual it must be cookies and browser.

We tried in Google which allowed me to get to login but would load customers, reports, vat, etc.  so tried incognito window wouldn't get to login.

We went back to safari and tried private window which successfully logged me in and is genetrally working.  now it's doing the same as google and won't load bank transactions.

Both browsers are up to date and both have all caches, cookies cleared (numerous times through this process).  Bit rubbish to be told that it's a caching issue and i must keep them up to date when that still hasn't resolved the issue and it's clear software updates happened yesterday! (Big giveaway with all the prompts on the menu!!!)
I Still can't access the mobile app on my ipad (Tells me session is expired and then sits on exit)

I can access mobile on my phone but it doesn't have all the functionaility i need to do my business.

So been told they have to monitor the issue. Really really unimpressed!
