If your experience with Dubbel has been less than ideal, it may be because your phone is 64-bit. Issues like Play Services not being installed, crashes, etc. are due mostly in part to this.
I may have told you this in feedback previously, but we are going to release a 64-Bit Support addon for Dubbel that should address these issues. We are currently alpha testing it at the moment. It will have its own store page, which I will update in this ticket upon release.
Thank you for your patience. I know the ads may be unbearable at the moment, and we hate this state of flux as much as you do. We just want to make sure that we audit Dubbel with this addon and make sure that it helps prior to releasing it.
Thanks for using Dubbel!
