YouTube TV was working fine then one day I go to watch and I'm getting a 'Not enough space' error message even though I haven't installed any new apps. I deleted several apps to try and resolve the issue but I still get the same error message. My player sits directly next to my Internet cube so I don't think my internet is the issue. I also play other apps just fine. I'm only get the message with YouTube TV.

That often is a symptom of a corrupted memory cache. This can generally be cleared up by restarting the Roku.
Depending on your Roku model you'll find the "System restart" option under "Settings > System > Power", or on models without a Power option, under "Settings > System".
Note: If you have a Roku TV with "Fast TV start" enabled, turning the TV off and back on just puts it into and out of a standby state and does NOT give you a complete restart. Use the menu option above.
If a restart doesn't do it, or if you don't have sufficient control with the remote to navigate the Roku menus, you can also restart by pulling the power plug to the Roku for a few seconds then plugging it back in and waiting for it to restart.

Re: YouTube TV not enough space
Yes, I had the exact same problem with not enough space error. I did the System Restart which immediately resolved the problem. YouTube opened up immediately when prompted. Thank you so much.

Re: YouTube TV not enough space
Yes I had the same problem as well, except my error message read, not enough memory. Mine showed up right on the Home Screen when I tried to go into an app. I also used the fore-mentioned solution using the system reset, but my tv did have the fast start on so I disabled it until it restarted. It worked like a charm! Thank you!!
