No controlled resistance after a break

I planned a 20 mile free ride today. Midway through, my toddler was calling for some milk, so I hopped off the bike and went to make some. It took no longer than 5-7 minutes. When I got back on the bike, I found that the trainer was no longer controlling resistance with the gradient changes. I un-paired the trainer and re-paired using FE-C and ANT+, but neither of them gave me any resistance control. It wasn’t until I ended my ride and loaded up Zwift again that it fixed the issue.

Using a KICKR Snap '17 on a desktop PC. I’ve been having random issues ever since the most recent update to Zwift. Any way to keep this from happening in the future?
