My first post so please forgive me if this isn’t the correct section.
I purchased ST a month or so ago and was able to put in custom messages with no problems at all. Within the past week, I can no longer enter any custom messages in. When I try and save I get this error “failed to save page: mainpage”
I can still use all the pre-set options, like dog bark and fire alarm.
I too am experiencing this problem. I think SmartThings has done something on their back end to combat people like you and I who are using the source code. I’ve been emailing them about this issue and they said they are re-working there TTS system and will be re-releasing the app later.
Just got this from support:(I give them credit for being honest as this just shows you they are under a tight budget and cannot extend capacity).
