Log in Issues with Client (6-7 Months no resolution)

Hello, i have had an ongoing issue for about 6-7 months and i’m getting quite frustrated with the client.

Basically i have two battle net accounts i regularily use, and the whenever i logout from Starcraft II, the client immediately without any prompts logs me into a specific account. Ive looked everywhere for related bugs or maybe a setting i ticked off somewhere but cant seem to find anything, if anyone has any information i would be pretty happy to know,

Thank you

Are you online on Battle.net on one specific account?
If yes, then well. Game will try to log you automaticly in game for that account. I couldn’t find an option to turn it off, perhaps somewhere in SC settings you can disable autologin?
