I have been having the same issue with the newsmax app on roku, but not on all of my roku devices. I have tried going back through the roku home menu and choosing newsmax again, which works sometimes. I have also tried restarting the roku for the particular tv that has the problem, and that works sometimes. On the tv with the worst situation, the only thing that has worked so far is resetting the roku cache by using the following manual sequence on the roku remote.
Restart roku and clear cache
To start, press the Home button five times, then the Up button once, the
Rewind button twice, and the Fast Forward button two times. Wait until
your Roku turns off and starts back up.
When doing the sequence, it will take several seconds for the roku to turn off and restart. For a normal restart through the system menu, the restart is faster than with this manual sequence, but the sequence worked and I was able to go to the newsmax app and resume streaming newsmax once again.
By the way, for those of you getting frustrated with entering long and cryptic passwords, I have discovered a relatively easy way to do it - copy the password you need to enter into the roku remote on the device like a phone you can use the roku app on, assuming that you have installed the roku app on your phone or device. It also helps to have a clipboard app on your phone or device that you can retrieve said password from when you will need that password, because most devices with a clipboard clear said clipboard after 15-30 seconds or so, but with a clipboard app you can go back to the app and retrieve whatever you recently copied into the clipboard, because the clipboard app maintains a buffer database with the last bunch of things that were copied to the clipboard and therefore makes it easy to retrieve what used to be in the clipboard even after the clipboard has been erased.
Now, once you have said password copied to the clipboard, go to the roku app on your phone/device and connect the app to the roku that you are trying to log back into with the long and cryptic password. When you are ready to enter the password on the roku remote, get the remote back to the password area on the roku tv screen. Put the roku app into the remote mode by pressing on the remote icon on the roku app screen. Then just paste the long and cryptic password into the space on your roku app while it is in remote mode, and said password should magically appear where it should in the password space on the roku tv screen. Voila! No more going through the roku remote and manually typing in all those password characters! Spread the word about both the roku cache clearing sequence for the roku remote and for how to easily paste a long password into the password space on the roku tv using the roku app and the clipboard/clipboard app.
