Hi @TechNoMad69 and thank you for the post.
I've checked our logs and for the first match you've mentioned, there were indeed 2 instances of you getting disconnected from the match; resulting shortly after in the match completion. If you get the network warning message, then there is usually something preventing you from communicating correctly with the server.
Make sure you don't have Bluetooth activated at the same time and, if possible, switch to a different connection to ensure it won't happen again.
