I think this is a server side issue. The wide swinging is back on left-drive roads (London, Makuri and Harrogate) and I think last time they fixed it server side. Something has definitely gone wrong at Zwift HQ and it looks like they’ve rolled back to an earlier version which might explain why the progress bar has also disappeared.
Although, from the outside, it’s hard to know exactly what is going on in Zwift HQ. I don’t think even the people that work there know what is going on in Zwift HQ.
