Hi all,
Thanks for your comments and I'll try to answer them.
Firstly, I was thinking I could share just access to the ATOM screen with a couple of good friends, purely for them to see what I can see in real time. If there was just a link to that, I would direct them to it. One friend in particular I've known for 40+ years and I completely trust him. He's an avid user of all the readily available flight-tracking apps and we often exchange screen-shots, but I just though an ATOM feed for him would be good. Anyway, if there's potential security risks to the system, I won't bother.
As for phone type, Android version etc. it' s Motorola G6 Play, Android V9 and Google Chrome browser.
I tried the VRS tab as you suggested thanks Lee and lo and behold the ATOM server is down. I'm having ongoing issues with power outages and after resetting the power today found I couldn't get the ATOM screen to work. This seems to be quite a frequent issue, but I just try again later and all seems fine...usually.
I didn't know the usual buttons seen on the local access screen didn't work when accessing through the remote login, but I do now.
Hopefully when the ATOM server is back up again, I can see it from home on my local network and remotely via remote login via the link.
Many thanks for all your help,
Frank.
