Hi!
I have SP Server 2019 with latest updates. Now i faced the problem when trying to check in document in modern experience library in web UI in Chrome. When I choose in doc's drop down menu "Check in" and then press submit button in pop up, nothing happens - document remains checked out. When I try to write comment for new version in the pop up window, it just disappears.
When checking in document in IE browser or trough MS Word Client everything is OK, so it is only for Chrome, but most of the users uses Chrome. And one more thing - in classic UI works even in Chrome.
Has anyone faced the same? Can it be bug of the latest update?
