Same problem, had to go back to 2020 to be able to use the feature normally. One weird workaround is if you try to update one file in Share For Review, then try to update a SECOND file the second one will work, and the first will produce an artifact error.

I don't know if this will work for everyone (I'm on InDesign 16.3 on a Windows 10 PC). Not ideal, but it's a workaround for anyone who needs their files to be able to update ASAP just make a dummy doc, try to update it, then update the one you need to work. Hope it helps somebody out there!

This is a killer issue for some people.

Same here, on both Mac/Win and 16.2.x and 16.3.x.

wheel spins incessantly upon opening a new indd doc or launching indesign. I want to turn it off!!!!

I am having this same issue in InDesign 16.1 after using the share for review feature successfully for an hour or so. It gets stuck on the spinning circle and then the window closes itself.

Same problem here. The issue seems to happen when updating the link. I'm using InDesign 16.1, MacOs Mojave 10.14.6, Chrome 89.04

I'm having a similar issue just now. It is so buggy. Sometimes it works and then sometimes it doesn't. Since this is a feature I use for my job to get projects approved, I need it to be consistent and signing in and out won't always fix it.

I click on share to review. When I go to update the link, the wheel just spins and spins. It gets stuck and will not update my link. I've tried signing in and out of creative cloud, which has worked before, but it isn't working now. I can't get the latest version of my document to my client because it won't update.
