Android 7.0 / Rachio 2.8-233
Been using Rachio for a year and never had an issue until today. Tried manually starting zones from the app but after selecting the time and tapping on run it would just go back to 0 right away.
Starting manually from controller worked fine.
Rebooted phone - same issue
Finally went into app manager and cleared Rachio cache and data. After going back into the app it started working fine.
