My battery died in my foot pod so obviously I replaced it, however since doing so my foot pod keeps slowing my pace randomly - i.e I'll be running at a steady 12:00 min mile pace on the treadmill and it'll randomly drop to like 18 min miles... I'm not sure why - I calibrated it recently as I bought a new 935 (had the same issue with my FR235). At one point it even dropped to a 25 min mile pace... Any tips on how to prevent this as it is making my indoor workout data very unreliable :/
Here is an example - I walked for the first minute, then ran at a steady pace for the first mile before taking a 0.25 mile walk break. I then ran at a steady pace for 0.45 miles, walked for 0.30 miles then ran at a steady pace for 0.75 miles - but looking at the last run section it looks like a lot of slowing down which didn't happen - I kept looking at my watch which was showing 18+ min miles.

Previously it had been spot on with my indoor runs - https://connect.garmin.com/modern/activity/1742025812
Many thanks
