Google Home does not update with new devices

I have the same issue but can’t access the solution proposed by @mrgneissguy: In “SmartApps” I see “The Google Assistant” (not “Google”) and under “Manage Devices” there is just a message that says “To manage your devices, open your Google Home app and select Home Control from the side menu…” All I seem to be able to do is “Tap to uninstall” and re-link to get new device list.

Google and SmartThings recently tried to upgrade their integration, but it didn’t go smoothly. Devices were supposed to sync into Google Home automatically from ST, but that wasn’t the case after they rolled it out.

The issue has been (mostly) corrected, so an unlink/relink of SmartThings in the Google Home app is necessary to pull the latest changes down. Once you unlink, the “Google Assistance” SmartApp in SmartThings goes away, and the new “Google” SmartApp replaces it when relinked. In that new Google SmartApp, you have the ability to selectively pick what devices and routines you want to sync into Google Home (which happens automatically a couple seconds after you select them).

I said “mostly corrected” because some UK/EU users are unable to re-link after they unlink ST and Google Home. That seems to still be an issue, but ST support is aware.
