There are too many glitches. The game persistently crashes. Error 17 messages. Pink pixelated frozen screens. I've given up with the Watch Ads as they don't give rewards. The cap on the Mayor's Season is a disincentive, What's the point in trying to get points in a league when there's a cap?
Why should I make stars to make other items to upgrade buildings I don't want? There have been no buildings in the recent seasons I want. The pretzels, pumpkins, snowflakes etc are annoying.
I've made my regions pretty, but I can't be bothered to change my capital now.
My team has lost several long time players. Engagement in weekly war has reduced.
I've no idea what the new services are as the screen freezes and anyway, there is no incentive to improve my capital. The city report is pointless. The global market is mostly unavailable and has huge, eye straining icons.
If you want to improve engagement, fix the glitches.
Make epic tokens easier to collect (like neosimoleons).
Add more land.
Remove the cap on Mayor's Pass.
Improve rewards so it's an incentive to buy the Mayor's Premium Pass.
Ensure the Watch Ads work.
Stop the gimmicks and the dumbing down of the game. We're mostly adults who play this, not kids!
