Upcoming sessions stuck on "... Searching ... "

[Meregill@btinternet.com]

Hi

for some time now, every time I go into "Find Sessions" and "Upcoming", I get a ... Searching ... which never resolves. Open jams shows anything happening ok but Upcoming seems to have stopped working for me.
I've tried reloading the Jamkazam App - I'm on Windows 10 - but it hasn't helped. Jamkazam version is Build 2.00 - "1.0.4048".
Can anyone shed any light on what could be wrong, please?

Many thanks
Chris
