Over a year later and this is still a problem for me and my ipad pro 12.9. I don't recall it ever working properly despite many updates over the last year.
I have the same problem, I can't get two together. Sometimes I win an extra colour bomb by watching a video, but they never end up next to each other and i'm unable to move onto the next level. Playing the same level over and over and over and... is no fun at all.
Wasn't a good update for me. On one of my devices that whole section (the cup) with build a bot and special events is no longer there at all. I was able to continue on my other device when I ran out of lives (playing the space race), but now that's not available. Not sure if it is being removed completely for some players.
I think it may be possible to beat every level without using any boosters as long as you keep trying and get a very lucky board. I was stuck on a very hard level and never got anywhere near collecting all the requirements till one lucky board got me to the point I had one more marshmallow to collect with one move left,…
One thing I don't like is that there appears to be some players who still are able to build up their boosters by playing previous levels as build a bot hasn't been rolled out to everyone (which is really unfair).
I find it is impossible to read some of the numbers too, it should be bigger. They spend too much time making the background look good and forget about the basic game functionality.
