I went to Support > the the only option is Visit Knowledge Base, then search produced no results for bug report or Android app, so scrolled down and didn’t find anything, so searched for support, which returned a page with the ‘submit support request’ link.
Then I was confused because you have to click on a homey device before you get the Mobile app support option in your picture, whereas the bug isn’t about a device
“I will forward your report to Development so they can take a look at it and try to fix it as soon as possible. I can’t give you any guarantees on when your issue will be found and solved, but please know that it will be placed in the right hands and will be investigated. For now this is all I can do for you, which is why I’m closing your ticket”
Kind of bizarre to declare a ticket closed at the point of being submitted, but I suppose not inconsistent with the rest of the Homey support experience
