Thanks Neil for the explanation which wasn’t a reason that I’d considered, but does seem to be logical
Several responders have used terms such as annoying, one described it as as a PITA & I have to agree with those sentiments. Is there a longer term plan to improve the situation? I’m inclined to think that having found a large number of new members, you would like to keep them. If the situation doesn’t improve though, I wonder if they’re going to stick around. As has been mentioned, it doesn’t seem to happen on other websites & probably will cause some to jump ship & go elsewhere.

This problem pops up now and again and there's a tendency for victims to assume 'it must be the website'. It ain't necessarily so.
A strange feature is it doesn't effect everyone – far from it. Instead, seems to afflict particular individuals at random, and it happens to them in clusters. There doesn't seem to be a particular combination of ISP, Browser or Operating System involved.
The site uses two different mechanisms to control logins; one allows the server to zap logins, as might be necessary to shed users during busy times. But I would expect server end disconnects to be relatively unusual.
The symptoms suggest to me the problem lies at the user end. The second works like this: after a successful login, an authorisation cookie is stored on our computer's disc. The cookie, which is time limited (several months) lasts between sessions and is used to re-authenticate behind the scenes later. The system relies on a successful network handshake between the website and your computer.
Our computers are a likely source of error and there are many possibilities, particularly as none of us really understands how our machines are set up. We rely on Installs, software and hardware to generally behave without having to grip any of the detail.
And computers go wrong! Issues with the home computer's configuration, perhaps over aggressive Anti-virus software, or Browser settings and misfiring plug-ins can cause cookie problems. Malware has a taste for cookies, as does the O/S reclaiming disk space, and other 'tidy up' applications. Clock errors, security certificate glitches and network problems can also cause trouble. Very difficult to diagnose.
Unfortunately although I have the tools needed to have a chance of tracing the malfunction, I've only been logged out a couple of times since 2015, and never persistently! I'm quite active too – 5700 posts and 1700 photographs. I run Ubuntu mostly but also Catalina, Raspbian, and Windows 10 without any bother. Windows 7 was OK too. I don't have a Smart Phone or Tablet. Whatever the issue is, I don't have it. Grrrr.
Before dumping the Forum in disgust, I suggest checking your computer, which is worth doing periodically anyway. Try scanning for Malware with a different tool, experimenting with Browser settings and plugins, and looking at the machine's network error rate and memory consumption. People with the problem sometimes get it on more than one device at the same time, which hints at a network or router problem. (Try rebooting the router – they cause some very strange symptoms.)
Would be good to pin down the cause – must be ******* annoying!
