PixPix Image Editor

Hi, this app is great and easy to use, but it has one problem, although there are buttons to communicate with them or call them, but when I click on the buttons I am not redirected to any communication page..! I tried via email but it is difficult because there are no buttons to communicate with them via email..! My question is... I am subscribed to the paid plan, I tried to find a way to remove watermarks from photos but to no avail..! Does this app provide this service as well..?
