App crashes my iPhone SE & 7

I have the paid version of this app ($3.99) on both my phones but after updating to iOS 10.3 beta last evening it doesnt work AT ALL anymore. Just shows the opening page and freezes the entire
Phone there. Please come up with a patch to fix this as this is one of
My favourite apps! Thanks.
