Your friendly reminder (since I only just realised too) - April is testicular cancer awareness month it seems.
If you ever needed an excuse to give yourself a jolly good feel around the balls, this is the month to do it.
I can only assume it's a case of "If you're a VΓvoactive 3 user, you're not serious about being an athlete and thus you do not deserve full data" which happens sometimes :/
I've been tempted to combine footpod and GPS outside since I'd like semi-accurate cadence data too, and I've noticed my VΓvoactive gets cadence iffy if I have to wipe my face or drink water without the footpod.
Please do, and file an issue, we've managed to resolve all the proxy-related issues recently with 1.18.0 so hopefully it won't be too hard for us to fix stuff for you too.
