Companion app crashed 10 minutes into a workout and the full workout was lost

This morning, the companion app froze up during a workout. Tried restarting it several times but it wouldn’t pick up the session.
I finished the 1:40 workout, saved it using the Zwift app on my laptop, but only 0:10 was saved and not as a workout.
Very frustrating as the training plan still wants me to complete the session.
I cannot redo the session as I’m industry for a conference the rest of the week.
This sort of thing just shouldn’t happen.
Please investigate and fix.
