Re: There’s Not enough memory now
Those inadequate memory warnings are often a symptom of the Roku memory cache getting corrupted. Deleting channel app after channel app does not make the warnings go away. Clearing the memory cache should cure the problem.
The easiest way to do this is to RESTART your Roku. (For Roku TV users reading this: if you have "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, so use the methods below.)
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".
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.

Can't watch streaming channels. It says it doesn't have memory or space to install.
Coming back from vacation and when we used roku remote and clicked on our streaming channels it says Not Enough Memory Not enough space to Install. Had no problems until we came back. Is there a way to trouble shoot Roku? The connection is good. Could the roku device be bad?

Re: Can't watch streaming channels. It says it doesn't have memory or space to install.
Do either a system restart on your device or unplug it from power for 60 seconds in order to clear the cache.

Getting error of out of space and need to remove apps
Over the past week or so I have been unable to open my apps. I get this message saying that I ran out of space and need to remove apps to try to free up.
I did delete unnecessary apps and ones that I do not use. Im down to six apps that I do use and it still says I am out of space.
I really don’t know what else to do or what the issue could be. I haven’t added more apps for it to run out of space. I do know updates could have taken more space, but doubt it was enough for this issue to come up.

Re: Issue with Roku saying I ran out of space
When a channel/app has issues, especially memory related, the best thing to try is either doing a full system restart the device or unplug for 60 seconds to clear the cache. If you are uninstalling the app, uninstall then do a system restart or unplug power for 60 seconds and then reinstall the app.

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!!
