Wattbike Atom links to Zwift but huge resistance and very low speed

Hi.

Went to go on Zwift this evening. The Wattbike linked quickly as usual, but when I went to ride I encountered huge resistance and could only get to 2 or 3 mph max. I’ve used Zwift for several years using my iPad without ever encountering this problem. I rode yesterday ( New Years Eve) without any issues.

I use iPad with lightning adapter into TV. iPad is old, operating on IOS 16.7.12. I switched everything off and re-logged in, but no success. I then linked to the Wattbike app and did a ‘Quick Ride’ and everything worked normally. 3 miles at 18.0 mph at 187 Watts. Gears all good. No sign of any update needed.

I know that sometimes it’s best not to rush in so just left it and will try to sign in again tomorrow morning. But if any thoughts this would be appreciated. As before, my set up has been v reliable for a very long time. Worried that iPad no longer allows App updates is one thought.

Will update tomorrow morning when have tried again- thanks!

Hi again. Just been out to the garage and loaded up Zwift and all is back to normal thankfully! Logged in three times and each time all was good. Guessing just a glitch with Zwift itself yesterday. I’d switched iPad off yesterday to clear cache etc. (I do this regularly in any case). BW
