Thankyou for that advice. After being offered VPNs etc etc I have downloaded Opera which now appears to work. The browser ( ?) that wasn't working was Google...I think...?
Nope....not working on my Android phone. Frustrating as I'm not a techie and not back to the UK until the end of the month. Why do people find it necessary to keep tinkering with a system that appeared to be fine...?
