The transfer notification time is too low (90 seconds). By the time I have to log into my phone (password etc), load the app, and possibly purchase more cash (because the bidding went much higher over the past few hours while I was away), 90 seconds is up and I lost/wasted tokens.
The same with game reminders. Most of my games are during the day when I am at work. Most of 15 minutes have gone by before I see the notification, especially if I am really busy working. Every 15 minutes starting 1 hour before gametime would be cool.
An email reminder would also be nice. If I dont have my phone, but am online, near email, an email that pops up would be handy to get.
