I just went to roku.com, clicked Sign In, then clicked forgot password, and it asked me for my email address only. Then it said it sent an email to me. (I couldn’t check that since I used a made-up email since I didn’t really want to reset my password.)
So, at least until that point, no previous password was requested.
It’s a little hard to follow your post because it starts be saying your password was changed. (already.)
If you’re trying to do it all on a phone, those can be confusing, but even phones from 10 years ago could multitask. For example, on Android, with icons on the bottom, you press the task manager (usually just a square in stock Android) and then you can swipe between your messages app and your browser. Unfortunately, Android allows OEMs to change the appearance of those buttons, and your phone might be set to use gestures instead of the fixed row of icons. So, I’m sure your phone can do it, even if the variations of android make it hard to describe exactly how. Apples have similar things but always with gestures, I think.
If it’s all too confusing, try the password reset on a computer and leave the phone for just the 2FA (code) part.
Then again, after typing all that, I wonder: How are you posting here if you can’t reset your password? Do you have more than one Roku account?
Oh and you say: If I go through www.roku which makes me wonder where else???? you were going to reset a password.
I hope my confusion hasn’t confused you more!
Banned but back. Because why not?
