Do SiriusXM Lifetime Subscription radios ever need a refresh?

[GroundLoop]

Have two Lifetime Subscription radios. One of them just went to the Preview channel. Did a "refresh my radio" and now all the channels are back. This did not happen to the other radio. The one that went to the Preview channel is a newer radio. Have had the one Lifetime Subscription radio for almost 10 years and never had an issue. Do Lifetime Subscription radios need occasional refreshes?

I've had my life subbed receiver need refreshing after long periods of no use when I was spending a lot of time in the hospital. I keep the number in my cell phone with the receiver number noted.
