Sent to Home screen at the start of a Competitive Match

Twice this season, I have been kicked to the Overwatch home screen at the beginning of a competitive match. The “rejoin match” option is there, and when I click it it brings to the game, but sends me back out causing me to immediately lose 50 SR, as the match already had already began to cancel. I do not believe the cause was my internet connection, and that is because during events where I was disconnected due to an actual internet problem, the client sends me back to the login screen and not the main screen, and I am also not able to do other online functions. In the occurrences in which I was sent back to the main menu, I was also still online on the Blizzard launcher, and able to join a quickplay match immediately after the “rejoin match” text had disappeared. Not being able to play comp for ten minutes, and losing two wins worth of play is not very fair for an error that is not even of my own fault.
