Roku setup

[KZ2]

My MLB app no longer works on Roku device but works on all others. I have removed the app and installed it again. I have unplugging the modem and restarting it. I have reset the Roku and that has not worked either. Now what? Why doesn’t Roku have a customer service phone number? How irritating especially at the beginning of baseball season.

@KZ2-

After removing the channel, but BEFORE reinstalling it, did you RESTART** your Roku to clear its memory cache?  Without the restart you may not get a clean reinstall.  This is not a cure-all but at least it will assure you of having an uncorrupted copy of the current channel app.
 
Depending on your Roku model number you'll find the "System restart" option under either "Settings > System > Power" or under "Settings > System".   If you don't have sufficient control to use the menus, or if it is just more convenient, you can also restart by pulling the power plug for a short while, then plugging it back in.
 
**On a Roku TV with "Fast TV Start" enabled, turning the TV off/on only puts you in/out of a low power standby state, it does NOT give you a complete restart.  Use the methods above.
