Zwift crashing midsession

For the last few weeks, every couple of rides the Zwift app crashes midsession and I lose my workout. It’s very frustrating…

I have had the same issue - it has happened twice on the Innsbruck route over the last couple of weeks and once in Yorkshire (this morning). I have had to restart the app, and click forward to get to the correct interval in my workout. Yes, it is frustrating! But I haven’t seen anything on the forum yet that indicates what the problem is or how to solve it. (I am on a Mac, and run the companion app on my Android.)
