Smart Lock Guest Access - "Couldn't download"?

I’ve been using Smart Lock Guest Access in the new SmartThings app for a couple of months now and have been having an issue with it lately. I can no longer Lock and unlock my deadbolt from the app (Schlage Z-Wave Plus). In addition, when I tap on its heading or anywhere in the tile other than the Lock/Unlock all button it gives me a pop-up message saying “Couldn’t download Smart Lock Guest Access”. Try again.". I believe that it used to show me the status of the Lock (online, offline, etc) when I tapped it. You can see the message at the bottom of the attached screenshot.
Oddly, when the lock is manually toggled I still get the notifications for it.

I don’t see a way to remove the Smart Lock feature so that I can re-add it. I so have the deadbolt set up in the old app with “Smart Locks” and it’s not working there either. The only thing that has changed is that my phone updated to Android 10. Could that have something to do with it?

Any ideas? TIA!

Edit: Using the SmartThings v3 hub.


Try to uninstall it and reinstall it from the Automations page, click on the 3 dots and delete.

Alternatively if you have access to RBoy Apps, you can try LUM: [RELEASE] Lock User Management - Door lock code manager (create, delete and schedule codes) with automatic lock/unlock, custom user actions and SHM/ADT integration (LUM)

Thanks for the tip. I tried that and it still gives the error. :confused:

Looks like I may have to check out the Rboy stuff!

i’m betting on android 10. There are some known bugs with the SmartThings app and Android 10.

Got the below response to my message to SmartThings support, confirming that it’s an Android 10-related issue:

Same issue. Pixel 3/Android 10. Select the Lock App and receive ‘Couldn’t download Smart LockGuesy Access’. Removed app and reinstalled, same issue. Automation for that app is currently broken. I’m interested in when they fix it.

Yes, this needs a fix for Android 10. I’m going on vacation and need to add a guest code. This is an important function of the lock

I was able to add and delete codes via the classic app. The name assigned for the code doesn’t show up in the notifications, but at least I can add a code for now if needed until they fix the new app.
