### 1/5 — No support / not clear how to get help

*2026-02-25*

I’ve setup a lot of devices. I run Apex and a slew of other connected devices in my house. This app and the orca are unusable. It initially connected and then now just flashed and says device disconnected. No idea how to get support. The YouTube videos are only for a normal working device. No way to reset or anything. Wish I had t purchased.
