I just created a new tab on the Fitness page with two large Totals tables. I opened about half a dozen athletes (each in a new browser tab) to review and compare the numbers, but after opening a few of them, the custom tab disappeared entirely.
I’m not sure what triggered this behavior, but it seems related to opening multiple athletes with that custom tab configuration. This time, shift+F5 didn’t the trick.
Has anyone else experienced this, or is this a known issue?
I can’t believe I will have to make it all again
