Too many ads

I was just trying to look up words. But it’s constantly throwing ads in my face. Asking you to upgrade. I didn’t like that.

Suddenly French English dictionary not working

I’ve been using the Oxford hatchette French English dictionary for over a decade. Suddenly, it’s not working when I try to open it up. It just says “not connected to the Internet” which I am.. additionally I am unable to find that dictionary in the Apple Store; I did buy it many many years ago, and no other dictionary comes close in usefulness.
Can the developers please help?

Great app

Lots of information! Highly recommend.

Yikes.

Can’t even look up words without being bombarded with ads. The app becomes aggressive when you choose not to go with premium. This is definitely want the owners wanted but honestly, the aggressive ads is disgusting.
