I'm seeing a 'similar' thing too (Desktop, Windows 10, Chrome). The last few days, I get a message saying it wants to check if it's OK to connect my browser. It pauses for a few seconds, and I guess it decides everything is OK, and away we go. I thought it was the new version of Chrome, but maybe it's something in the way the forums
are set-up. Whatever, it only seems to happen the first time and all seems well after that.
