I know this is a bit of a me too post, but me too.
Setup 2 blends over the weekend, and when I enter either of them there is a circle in the top left that looks like it's trying to do an animation. It shows a red dot with a fainter red dot behind it. There is a green progress strip around the outside. The progress gets less than a second in, and about a quarter of the way around the circle, and the whole thing stops and the progress bar stutters moving backwards and forwards. At this point, Spotify has crashed and all I can do is force close it.
Hey so i have the same problem. The solution i found is to scroll down as soon as you open the Blend, wait a few seconds and then it'll work normally without crashing. Otherwise the animation gets stuck and the app becomes unusable.
