My account 1 has no matches, but account 2 does. Both accounts must pass 22 levels before they can obtain the legendary ball. Episode Race and Rocket Dash are the same as usual.
Have you cleared the game cache and "restarted the phone"? Whenever my task disappears, it will appear after the phone is restarted. Please give it a try.
FHS's "Go to level" is very useful. In addition, since I personally have a "red/green weak" problem, I often can't distinguish the yellow and light green bubbles of BW2, haha.
Don't worry, I'm just sharing my situation. After three years of disappearing games, I have a completely normal attitude toward the game. Itโs great if I can participate, and it doesnโt matter if I canโt.
