Auto Pause Does Not Work In Indoor Bike App

I didn't say it was useless. I said I couldn't envisage a need for it when indoor training. My dog doesn't pee on the rug, but sometimes I have to stop my ride to answer the front door for a delivery. The bike may well come to a halt, but my heart is still beating, I'm burning calories and getting a little recovery. I could (auto)pause recording for 60 seconds or so, but I still don't see why I would want to. I still want to record my body metrics even if the bike has stopped.

Also, as a Zwifter, a descent of Alpe du Zwift can take over 6 minutes without pedalling once. It's all part of the ride. The flywheel might stop (it doesn't, since I have a Neo) but I want recording to continue, even if my power and cadence are zero. Same with any other coasting in game.

I guess it all comes down to why you are using the watch to record. What do you lose or gain by having or not having autopause. That's rhetorical, so no need to reply. For my use case the watch is recording data about me - my training load, heart rate, stress, calories, power, body battery etc.. I want those things to continue recording even if my training is interrupted. Zwift takes care of the cycling metrics - speed, ascent/decent, power, heart rate and so on. Those go to Strava. The watch data and Garmin Connect is used to monitor my physical performance and readiness to perform. Even interruptions all contribute to that data.

If it's an advertised feature and you want it to work I have no problem with that. It should, of course, work as advertised if you need/want it.
