Just noticed a small issue with the ToW Events filter in Companion (iOS 15.3.1, Companion v3.33.0):
Without the ToW filter applied, if I’ve signed up for a ride I see the usual green ‘Going’ icon and the overlay showing the time until event in the Events section:
After applying the filter, the icon/overlay aren’t shown:
This doesn’t affect the appearance of the rides in Events on the front page of Companion, but it somewhat defeats the purpose of the ToW filter in the dedicated section. 
Edit: am creating a separate Bugs and Support thread for this issue, with more detail
