Just to leave registered, I tested the 'copy and paste' way to solve this problem in a real video call yesterday (using Opera GX, only) and I it didn't work unfortunately, although it doesn't seem to be a Opera GX's fault.
I was on a actual video call with a friend and everything was going well with the popup window, so I have copied and pasted the window's link in a new tab and the video call loaded perfectly (at the new tab). But right after the loading was finished I had to click on Hangout's button saying Join the meeting or something close to that. After click on it, I was duplicated, i. e., there were two of me and one of my friend on the calling (no problem though) and I could make me be listened and seen, but I was able to only see my friend, not to listen to him... that was the real problem.
After some tries we gave up from this solution and continued to use two windows separately.
@jorakae said in Close WhatsApp Chat, how?:
In the web/PC version there is an ability to close an individual chat with an X on the top right as you would expect. However, in the Opera version, it seems I must always have a chat window open. I can't find any way to close just the chat while leaving the contact list open. In the top right of the chat, there is only an options button. Am I missing something here?
Hi jorakae I search on this issue little bit and I found this https://blogs.opera.com/india/2015/03/chat-whatsapp-web-using-opera-computers/ on google and I think this is helpful.
