UPDATE: March 17th patch appears to have fixed this issue.
After sending someone media (ie; an image), discord will completely remove focus from the text input area, forcing you to click back into it to continue typing.
It did not function like this before the latest update. I attempted to test if .308 suffered this, but discord force updates because they hate their users so I can't revert back and stop being livid over this issue.
Stop releasing broken updates.
Edit: Between 3 friends I asked to test this issue, 2 reported it didn't happen. They were on Windows 7 and Windows 10 v2004.
I have tested this being broken on W10 v1703 and v20H2. The other person who saw the issue didn't give me their Windows version.
It's possible this is only affecting certain users and I am clueless as to why. Adjusted multiple settings in Discord to no avail.
Edit2: One of those friends didn't understand the issue and thought it was something else. They do actually experience it.
I tested the web client and it also functioned the same; OS is irrelevant here.
I'm going to now assume it's the same for every Discord user, which disappoints me that there's barely any uproar about it at all when it's such a disruptive flow to our chat experience; notably those who send images a lot.
