Home App on iOS- Thermostat + and - not responding

[quinnwas]

A month back I could only raise Nest temp using the slider- iOS app didn't respond to tapping - or +.  True for thermostat temp as well as cutover temp set for dual fuel (where there is no slider and therefor no backup).  Thoughts on this?

Hey there,

Sorry for the late reply. I wanted to follow up and see if I could be of any help. Do you mind me asking if you have tried to reset the device? Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further. 

Best regards,
Jake

Thanks, Jake.  I power-cycled my iPhone to no avail, but have not re-installed the app, since I don't know if settings are retained and wanted to exhaust other possibilities.  Or did you mean resetting the thermostat itself?  This seems to be an issue with the app itself...  Thanks
