My Mac is running Big Sur 11.2.1 (20D74).
My iPhone is running iOS 14.4 (18D52).
They are both therefore fully up to date.
A yellow triangle is appearing on Reminders on both devices
Looking into this matter, it appears to mean the two devices are not synchronising with each other.
But they are!
So why am I getting this warning icon?
The_Knowledge_Seeker,
Have you upgraded Reminders for iCloud? If not, see if you have an update option available as described in this article:

Hello The_Knowledge_Seeker,
Thank you for using Apple Support Communities!
We understand from your post that you are seeing a yellow triangle next to Reminders in the Reminders app. This article has steps which may help:

Best Regards.
The_Knowledge_Seeker,
Since everything seems to be set up properly and you seem to have upgraded your Reminders you may need to contact Apple Support for additional assistance.
Take Care.
Thanks for your advice Alwayswantingtohelp1.
I've checked my setup and all looks ok based on that article.
The odd thing is that syncing works fine between Reminders on all three devices (1 x MacBook Pro and 2 x iPhone SE 2nd Gen) plus iCloud.com.
I just can't see why the warning triangle is showing.
I even turned Reminders off on all three devices (triangle disappeared) and then then I turned them back on, the triangle returned.
Do I just ignore the triangle? Or is it warning me about something else?
As far as I can tell, they are all using upgraded reminders; I certainly can't see any upgrade option.
