I'm not familiar with Nino's Corner, but typically channels that place limits do it on the simultaneous streams being requested, not number of installations.
I can't find any info on the Nino's Corner website to indicate which Roku models they support. Possibly they didn't write their app to run on some older no longer supported Roku models. What are the model names and model numbers of the devices that do and don't receive this channel? You can find out via Settings / System / About on each.
Typically, if you can go into the Channel Store on your Roku device and are able to find the channel, it is compatible with that device.
