Blondesister review for Growave: Loyalty & Wishlist

I'm currently using this app but I don't think I'll be using it for a long time, the inability to customize the rewards page is really limiting. In addition to the fact that it is not possible to have a LOGIN button when loading the page, which makes usability compromised by the user, because to log in he has to click randomly inside the page to see the log in button. I asked to make this button visible right away, but it seems impossible to implement. I'm not satisfied at all.
