this is odd.
I download the last snapshot yesterday but the build shows Mar 7 2022 but yours is May 20 2022. Same 4010 build.
Not related but worth noting it says OS: Windows 10 Version 2009 but I'm on W11.
Nonetheless following your email I did another test creating a new workout containing just that one exemple ( 4x4m@260r4m@95L) and it worked...
After the I tested the workout that had present the problem and it worked as well.
But something has happened because it was VO2 max workout and I was coming back from a cold and couldn't handle the intervals and when I pressed next lap it was going to the next VO2 interval instead the rest ... It happened the whole activity... including the Anaerobic steps.
Anyway thanks.
I let you know it that happens again.
Best regards,
PS: is not that it was a new workout or the first time. I had done it dozens of times....
