For example, when adding an assignment with a download, sometimes an error message pops up that assignment cannot be added. Unfortunately that does not help. Through trial and error we figured out the download being attached had a character the system did not like. Should have been quickly fixed if we knew exactly what the error was in the first place!
This user cannot be deleted without further action pops up frequently when I'm trying to run merges from the POTENTIAL DUPLICATE USERS. That message is essentially useless without some info on what further action is required. In the absence of actionable info in the error message, I've repeatedly had to get into time-consuming chats, which eat up valuable time both for me and for your support staff!
I agree. One of the problems I saw was with custom forms. If you don't acknowledge the captcha, you get an error about an object reference not being set to an instance of an object. A simple "you didn't fill out the captcha" would be very helpful
