same here, not yet screenshotting PP2
there are five types of challenges to address and within each, the first match, mild, only gives coins but second or third will give Hot Date seeds plus 15 or 20 percent towards the Zomboss battle (ready when you reach 100%)
high level plants have no trouble winning any match but my Level 1 profile can only win mild or medium so far...without resorting to spending GEMs or coins on Power Ups of course !!
Zomboss has 3 battles and gives 10,15, or 20 Hot Date seeds per level of difficulty
