In the Android app, I toggled off Faster Assets and then switched to "renshuu server" from Global. I then switched those settings back. This is while I was in Quick Draw, if that's relevant. When I came back to my dashboard I noticed almost all my Kao Garden quests under Today had duplicates. (The ones under This Week and Permanent are normal.) There are 2 or 3 of each quest that got duplicated. There are also 9 different quests rather than 7.
Screenshots are from the desktop browser because that's just easier for me. This hasn't happened for me when toggling those features on desktop, though.
