Samsung Tab 8 Logging on to onstream

I have onstream on my 4K maxx. I upgraded it to the next version. However I had to log off the old app and log on the new app. Problem is I forgot my password cuz I never thought I’d use the app again so I didn’t write it down. The forgot password recovery on the onstream doesn’t work. So I logged on my tablet and the tablet went head logged me on on stream. The problem is I am logged off on Google and Samsung account on the tablet I have my accounts logged off but the dang thing still logged me on. I rechecked it got rid of all the permissions and it still logs me on. Anybody got an idea what’s going on here. Nothing is synced to my equipment.
