The new app has real performance problems, I have it on my two Roku sticks tablet and phone. It is really slow starting and has crashed a few times especially the android version. Also the inability to resume from where I leave a program has still not been addressed. The overall UI is terrible not at all friendly. The previous version was far better. Can't believe they didn't fix the resume issue at least 😡
Have you tried to delete the app and reinstall it?
You could always try unplugging the router and plugging it back it.
Whilst I do know these might not help, it’s worth trying as I understand there has been some issues with the rebranded “NOW” on Roku devices.
Mine does at least work, so during trying different things I found that if when your on the main page just press the star top right and click check for updates on the now app. Or remove the now app and re add it. That may at least get it working for you. Hope that helps.
Keep an eye on other threads such as this.
The issue is well known across the forum.
Unfortunately I don’t own a Roku device to test out.
So after several replies on Twitter from Now help account the final suggestion was to factory reset all my devices to see if that works. I said I was sure that it was the App that is the problem not every device I use, they didn't reply after that. Not the outcome I'd hoped for. So hopefully Now techs have a look on here but to be honest I doubt it.
