Continuing the discussion from SmartThings OAuth Changes:
The deadline for shared OAuth installs (like the SmartTiles web installer) has been updated to March 31st, 2016 (i.e., new restrictions are in place on April 1st.
Note: It is very important that you do not “Remove / Uninstall” the “SmartTiles (Connect)” SmartApp from your Account, since, for an indeterminate period, there will be no way for you to reinstall it.
I have posted more information on the SmartTiles News Feed:
##The (temporary) good news:
SmartThings has partially resolved the platform / system issues. They have added a new server cluster (AKA a “cloud shard”) with address “
https://graph-na02-useast1.api.smartthings.com/”, and we have updated the SmartTiles Installer to support this.
We are not certain how or which SmartThings Accounts are being assigned to the new Region-Shard, but perhaps it is used for all for new SmartThings customers, or customers who have deleted and now recreated their Accounts.
Regardless, it does not hurt to try multiple installation attempts, each time using a different choice of Region-Shard on the Installation Options Screen. The new option is the second one (see picture below).
We apologize for the inconvenience and appreciate your patience as we navigate SmartThings’s turbulent waters.
