Annoying unsilencable dialogs for internet connection problems

When starting thunderbird without a working internet connection, I get an annoying amount of dialog windows reminding me for each email message box/server that the connection can't be estabilshed. The german text is „Verbindung mit Server <server> konnte nicht hergestellt werden.“ (sorry, dont have the english one..., its basically „connection to server <server> couldnt be established“). One has to click "ok" on each of these warnings and there seems to be no possibility to silence them. I mean, I know that I don't have internet (or know that the internet is buggy atm, even if I retry to get messages.) To have a message at all could be okay, but it very much interferes with reading messages (which works fine with buggy internet...) as they just pop up. I even couldn't find any settings or configuration in the configuration list searching for anything containing „dialog“ or „connect“ (which would be my/the expected place for silencing any dialogs regarding connection issues.) How can I get Thunderbird getting to work with me again and not interfering with workflow? Best regards ________ I searched for dialog connection / dialog internet connection and didn't find any regarding topics problem occurs on 156.0.1 (64bit) Mozilla Thunderbird Snap for Ubuntu ubuntu-snap-build - 1.0
