Is the game crashing a lot for anyone else?

I've been playing the game seen it has come out and I have never had any problems with it until now. The crashes all started a few months ago and it has gotten to the point where it happens every minute. I can barely play the game right now and I don't know how to fix this. I have a ton of free storage on my phone and the DQ Tact app is the only one that crashes.

Is this happening to anyone else or is this just my phone? I have an iPhone 8.
