Warm Up Rides not registering when you switch to event/group ride

Today I’ve noticed that my warm up ride before a group ride isn’t registering. I ride 1-5 miles as warm up and then Join the Event and it switches fine but Zwift Companion doesn’t register the warm up ride at all so miles not recognised or an upload to Strava. My brother’s had the same problem. Is everyone getting this and is there a simple fix planned?

If your ride is shorter than 2km it won’t upload.
