Unless you have the model 3700 Express, I wouldn't think you would experience that. And, I wouldn't think it would make a difference. However, if you have the model 3700, it may be time to upgrade. The model 3700 is five years old, but has been an otherwise dependable device. Some apps will not run on it, though, particularly newer apps by some major services. And, it's not Roku, but the app developer that determines if it works on any particular model. Some have chosen to drop support for the 3700, but most still support it.
If you were to upgrade, the Express 4K+ has been reported to be an excellent device. It replaced the Premiere in the lineup (the middle of the line of boxes: Express, Premiere, Ultra). And, it's priced only a little more than the current Express, so it may be the best bargain overall.
