I used to have a roku express for 2 years, one day the apps started crashing so i went out and bought a new one. I now have a roku #Express 4k I just bought it less than 2 weeks ago. 3 different times now the apps crash. I system updated it twice and it was working for a few days. Now today 10/18/21 the apps started crashing, did a system update and still no app will ope
The first question is are you using the supplied USB power adapter and not your TV's USB port?
The second question is: what exactly do you mean by the apps crashing? Exiting and returning to the Roku home screen? Not loading at all? Something else?
The more information you can give, the better chance there is that somebody can help.
