Very similar to the issues I was seeing here : New core, new problems - #28 by Yarbo-Forum
I unplugged the battery for about 24 hours and then turned yarbo back on with the SAM attached. Thats seemed to work, so I switched to the SB. That seems to be working too. Yarbo magic.
I noticed in your post you mention is was 7F out when you had the issues. It was cold here as well, -24C (-8F) territory. The issues went away the same time as it warmed up. Maybe on to something….
