Emailed on June 4 about a broken collision sensor on my mower and haven’t gotten any reply yet from support. Used to get messages back in a couple days but nothing on far. Have had to be creative with no go zones to avoid yarbo being “aggressive” with running into things.
Yes, they are very slow right now to respond. I hope they get caught up soon
A lot of the support issues were inflicted by the dev team. There’d be a support vs dev cage match happening if I were in their position. 
Queue time seems to be about 7 days.
I’m sorry for the delay in our response. We’ve recently experienced a higher-than-usual volume of support tickets, which has unfortunately led to longer response times.
I’ve already asked the team to review your case as soon as possible. Thank you for your patience and understanding, and we’ll do our best to get back to you with an update soon.
