I may fix it, you know I'm working on Rule34 Browser cause I made it after X Comic with more experience and manage its code to make development much much easier than X Comic, X Comic code is very messy and its really hard for me to develop any more. I may create new app like X Comic with much more ability and sites but its gonna take time.
Sorry about it, but you can enjoy world of rule34 on Rule34 Browser app till I release new app like X Comic.
