Channels will not changes subscriptions

I have two subscriptions for channels dvr. I have signed out of my first account and signed into my second. Even after signing out of out of the first account the app still displays the first account and not the second account. Has anyone seen this?

Which app are you referring to?

Are the two DVRs set up with the correct accounts already? You should see the correct avatar and username at the top right of the web UI

This is channels dvr for firestick and it seems to not signout my old account for my new.

The signin process happens on the dvr server. Check the web UI on your computer where you installed the dvr and check if the correct username is shown on the top right of the page.
