Unable to log in to the account with the Roku Smart Home app

Apparently nobody reads the responses that come before their post.  A possible solution was posted above.  Give it a try:

If you don't have the Roku mobile app, install it and see if you can log into your Roku account on it.  If you have it already, but it's signed into a different Roku account, try signing into the same account as you're using for your "smart" 🙄 home devices.  For me, once I signed into the mobile app with the same Roku account that my "smart" devices are linked to I was able to sign in on the smart home app without even needing to enter a password.

Hi Community users,

We believe the issue with accessing the Android Smart Home app is now fixed.

We recommend updating to the most recent version, 2.7.1, from the Google Play store if you are having trouble logging into your account while using the Android Smart Home App.

We're going to mark this post as solved and lock the thread.

Thanks to everyone who reported this and for your patience while we worked with the channel partner to find a resolution.

Best regards,
Community Roku Team
