Ramp FTP broken


Just tried ramp FTP after a few months and it’s now broken. It wouldn’t engage ERG mode again after a drop out and when it came up for me to end I selected end ride on companion app and it did not save anything other than just as a free ride. Please fix and how can I find out the data it did get to calculate whatever the FTP result should have been?

Thanks in advance,

I did a ramp FTP test the other week without problem
