Best app for the job

Always making improvements it’s really a great ecosystem

Internal/external IP issue

For those that don’t leave location services enabled or don’t want to give location permission to everything, please allow a simple manual switch from internal to external IP or implement a simple failover, if internal doesn’t work try external before fail.

App doesn’t pick correct internal/external state without location services.

Thanks. Great app otherwise.

Fails to connect to my green

I can connect via browser from my phone but not from the app on my phone. No option to manually enter address just sits there counting down from 60 after failure.

Nice but…

Amazing features but they move things around making website and YouTube information inaccurate.
