Thanks @TommIR however the BETA says not appropriate for those in the APAC region. Do you know why this is? Should I go with the BETA anyway?
Sorry, I don't know but if Garmin says it is not suitable then probably it isn't and I wouldn't attempt it.
Maybe best contacting Garmin support but at least for the power spikes with firmware 6 they only told me about the official release fixing the issue about half a year since the bug report although the issue was fixed in 6.51 beta two weeks after.
From what I have read, they seem to publish APAC releases about 5 weeks after the official ROW releases with no access to betas.
I have the ROW version (European) and I actually had problems with the cadence sensor with 7.10 after all since it didn't connect or show any readings (first I just thought it ran out of battery) but that was fixed by upgrading to 7.52 beta and the sensor started working again. I had no crashes though.
