Crash bugs on iOS , and some of my opinions : )

I really like this game, it got so many options and so many powerful characters, but the best are the rewards. There is a bug I really dislike about this game, it crashes a lot. When I try to use medal scout, normal scout, edit party or choose a supporter, it sometimes crash immediately. Please fix this bug.

Also, I have opinions for the new characters oncoming for your next events. I think it will be nicer to have male characters more instead of female characters. There are quite too much girls in this game so how about we have more fun for Kirito and Eugeo? Thank you for being so patient for reading my review, I hope you can make the game better. : )

Constant crashing during gameplay

Hello developer, recently my SAO crashes almost every time, whether I go scouting, doing quest, checking character info etc. It usually just hangs for 2secs before proceeding to crash, was hoping it was a temporary bug which could be fixed but until today it still happens! I hope that you’d be able to look into it and solve this ASAP cause it affects my gameplay greatly. FYI, I’m using iPhone 6 - iOS 12.2. Appreciate it and thank you in advance.
