I've noticed that LinkedIn is mostly unusable with the latest RC on older OS (e.g. Catalina, Monterey). It allows login and the initial feed shows normally but clicking on something like 'Messaging' or 'Notifications' never comes back. The URL never changes from 'https://www.linkedin.com/feed' and it just hangs there. Even trying to open the URL of the 'Messaging' page ('https://www.linkedin.com/messaging' if I recall) directly doesn't cause that page to open.
Note that LinkedIn seems to work fine with the latest RC on Sonoma, etc. Also, the current Orion release [tested: Version 1.0.4 (143), WebKit 619.1.11.111.2] seems to handle LinkedIn fine on all platforms. I only see the problem with the latest RC on Monterey and earlier. I see it on both Apple Silicon and Intel (note I am guessing Orion for Ventura might have similar issues to the Monterey version but I can't test that).
I expected the LinkedIn site to work equally well across all current macOS versions (i.e. Mojave - Tahoe).
Obviously I can use LinkedIn on the current release version of Orion for now. Highlighting here so the issue doesn't make it into the next release version of Orion.
