I have found in chrome on windows I have to open an incognito browser session but then posting from ka72 to GPSTC works on the 2nd click. Not the first.
Well it did until I got banned for a month. Ooppss.
I tried that and it worked. It also works in Firefox. I reckon it must have something to do with chrome://flags but I didn't know which one to change.
Yeah I've had issues with not being able to upload for months so just started using www.gps-speedsurfing.com/ instead. There is interesting extra visibility and drill down available this this site too. For example you can view how fast people have been on specific boards and sails which is great when you buy second hand gear as I tend to.
