Howdy y'all,
We currently have a shared list setup which has multiple users, however one of our users regularly gets this error when opening the list - Something went wrong: Invalid argument: 'header's missing application ID header. He states he simply opens the list and the error populates, refreshing a few times fixes it.
For some reason I can't attach a image. But all it states is the error above with a spilt ice cream cone.
Thank you for any assistance.

I haven’t seen this problem anymore since the fix rolled out. Probably solved. Thanks everyone for pointing out!
when did the fix get rolled out to your environment? What country are you located in please?
Last monday. I’m located in The Netherlands.
I Still have users reporting it but gets resolved when they clear their cache.
Logged a call and the engineer could not find the incident when I mentioned it. SP664797
I got several e-mails from Microsoft about it for that number so it did finally get created, at least. But they did say last Thursday that it was "resolved for 100%" of customers:
