The ‘Zwifters Nearby’ has been broken for me for several weeks and I know many others have mentioned it in group rides / races. I have just updated to 1.42 and the issue remains.
The main issue is once I get to the top of the list I stay there forever, unless I scroll it manually. This is a real pain in a small front group in a race. Here’s a video of it happening: zwifters nearby bug - YouTube - as I slip back through the field I stay at the top.
Also at the start I usually don’t even appear in the list unless I scroll to find myself and sometimes it randomly scrolls off somewhere else.
