I'm not sure how to upload screenshots on here but I have sent some to CS, showing the same.
I've noticed that if you're free pass timer is counting down to your next free pass and the timer hits 00HRS 00M that's when it seems to make the Updating profile message appear when playing any game. If I'm just on the home screen and the timer hits 00HRS 00M then just the blue circle appears for a second or 2, but no Updating profile.
The free pass timer seems to be out and maybe connected to the issue as my timer can vary from saying 00HRS 15M to 00HRS 25M after it hits zero. It's also not counting down in hours and minutes, it's more like every 1 or 2 seconds.
The other thing that I think would have been better is where you have the Turf War icon on the home screen, once you hit it, it should take you directly to the current Turf War screen and not your club page.
Edit: The Updating profile message seems to happen when you use a pass. This could be very frustrating and time consuming during the clash as you have to use a pass to play clash.
I hope this helps.
