Monthly Challenges are not showing up.

I keep checking my watch and Activity App for my personal monthly challenge, but nothing appears! I had one every month up to and including November 2020, but I've had nothing after that date. I stopped using the watch for a while but I have been using it again for the past 6 weeks.

Please can someone let me know how I can get them to start up again - I really enjoyed them!

My notifications are toggled on. Daily Coaching too. Special Challenges as well.

I have unpaired and paired again. I have reset the watch as a brand new watch instead of restoring from backup. Both my iPhone and watch have the latest updated and both are connected to wifi.
