The only problem I have is whenever I add a stamp to my collection the App Store opens up and brings me to the page to download the app again. Is that a known issue, or is that what’s supposed to happen because it’s really annoying. It happens after every single stamp I add to the collection.",

Tried to identify a specific stamp, as I’m certainly no expert, that’s why I’m trying the app, and it showed multiple possibilities. Duh, what’s the sense? Do I have the dollar version, or the $1000 version?",

I get it, also It seems like a solid app, however as far as being “free” or even the first one to show up when using search phrase “free app for _____” …. Look elsewhere if you want “free to use“. Peace to my peeps.",
