Using Samsung Chromebook Pro and Starlink internet.
Whenever there is a brief outage or lag the editor screen is replaced by a pointless full screen "loading" page, then the editor slowly redraws the screen If I am lucky. Much of the time it logs me out over and over.
I lose at least 30 seconds out of every 5 minutes whether I typed any new code or not. If the code didn't change, don't reload the screen please. Sometimes I need to reread my code. That is impossible if my editor keeps disappearing or logging me out randomly.
It just did something similar while typing this message too. Said "Draft is being edited in another window. Please reload this page." No, it wasn't. Arduino Editor was the only other tab open.
Also, this machine has never connected to any Arduino in Chrome. They show up in dmesg and lsusb Linux Beta, and the Chrome system page, but are never functional. Genuine Uno, and several others tried.
