I have seen topics opened about this issue, but i haven't seen a proper solution to it. It looks like Spotify doesn't seem to care about it either. The problem is simple; you open the app, you see that your most listened Daily Mixes are on shuffle for no reason. I tried deleting the app completely, I tried logging off and on, I tried opening and closing the app repeatedly, it doesn't work. It gets worse after some time too, more of your Daily Mixes becomes shuffled and you can't do anything about it. And this is not the first time I'm experiencing this issue either, 2 weeks ago I had the same problem, it got fixed by itself, and now it came back. So please, fix this issue.
We just wanted to let you know that the right folks have taken a look at this for you. Right now, we're not able to provide an exact timeline for a fix, but we'd recommend always keeping your Spotify app up to date to ensure you're on the latest and best version.
