Hmm, you're right. Connection issues can indeed put a damper on a good Zwift ride. As for specific Bluetooth settings on iPads, I haven't heard of any hidden ones that could help with signal drops. But, I'll tell you this - some iPad models, especially the older ones, can be a bit fussy with Bluetooth. So, if you're experiencing frequent complications, it might be worth considering an upgrade.
As for heart rate monitors, I've noticed that some brands seem to play nicer with Zwift than others. Wahoo and Garmin, for instance, generally have a smooth connection. But, I've heard some horror stories about certain Polar models. It's not that they're incompatible, but they can be a bit temperamental.
Now, don't get me started on the whole firmware update thing. It's like a never-ending roller coaster ride. Just when you think everything's running smoothly, a new update comes along and throws a wrench in the works. It's enough to make you want to throw your iPad out the window!
But, despite these challenges, there's something oddly satisfying about Zwifting. Maybe it's the competitive spirit, or the sense of community. Or perhaps it's just the joy of riding without having to deal with actual weather conditions. Whatever it is, I can't seem to quit it. So, I guess we're all stuck in this frustrating, yet strangely addictive, world of virtual cycling together. :-/
