Ha ha ha.
The irony is not lost on me, that's for sure. The thing is, SmartTiles does not have access to your data. We never associate your email address with your Account or installation, nor do we track any authorization tokens, Location IDs or Device IDs.
SmartTiles runs entirely as a native SmartThings SmartApp (smart, smart, smart...). This means that only you (and SmartThings...) has access to your configuration data. This even makes diagnostics and debugging a challenge.
For Version 6, we've got ideas on how to securely store dashboard configuration information protected by a llogin password, and we hope will be better equipped to do or assist certain migrations when necessary. Migration from V5 to V6 ...
by the end of the year Nooooo!... just joking. Very very unlikely we can provide V5 to V6 migration. Just too complicated (frankly, more complicated than SmartThings Hub to Hub migration where all the data is in their cloud, fully, under their control).
