My Fenix 6S Prosolar has stopped recording my VO2 max, despite doing a significant number of outdoor runs and other exercise. Any ideas?

it was registering my VO2 max until 23 Oct and then stopped. I haven’t changed any settings and have done a number of runs, indoor cycles, weights etc but is isn’t registering. My training loads vary too. Everything else, all the various sensor measured indices alL work. Any ideas?
