As you can tell from the Mickey Mouse-shaped disco ball in the photo above, Season 31 of “Dancing with the Stars” (DWTS) premiered on Disney+ last night. This marked the first time the streaming service livestreamed a TV show. With instances of live TV apps crashing across the sports streaming space (looking at you DirecTV!), it's fair to say Disney+ felt the pressure to provide a smooth streaming experience for subscribers.

For the most part, Disney+’s livestream of “Dancing with the Stars” had minimal hiccups. Aside from a few minor delays and lags, the livestream performed well when we tested it on Monday evening on our Amazon Fire TV, PlayStation 4, Roku, and desktop.

But we won’t let Disney+ pat themselves on the back just yet.

A few subscribers reported via Twitter that the Disney+ app was crashing during the performance.

We also watched the livestream last night on an iPhone and had the same problem. At one point during the premiere, the Disney+ app failed to load, and all that was shown was a blue screen with the Disney+ logo.

This didn’t appear to be a widespread issue, however. A Disney+ spokesperson told TechCrunch, “we have not experienced or seen any spikes or reports of issues on our end.”

Even though a portion of customers experienced issues, it's important that Disney+ gives all mobile users a satisfying experience. In April, Sensor Tower found that Disney+ was among the top three most-used mobile streaming apps.

There have also been studies that point to more consumers--especially young consumers--using their phones to live stream content. Data intelligence platform Apptopia reported that 80% of 18-24-year-olds, 84% of 25-34-year-olds, and 55% of 55-64-year-olds watch streaming video on mobile.

It’s also worth noting that a potential reason why Disney+ didn’t have any major crashes is that there may not have been a large influx of viewers rushing to the streamer to watch a nearly 17-year-old franchise that, in recent years, has earned low ratings.
