Great app, a few issues

I love the app it usually works well, but I am at the point where almost all of my friends have stopped working. I just can’t rescan them, it will let me press the button but it doesn’t actually do it. I have uninstalled and reinstalled but it did not fix it. I also have the issue with if I press the send all button, it tells me some of my people on the list are not my friends, but I have scans with them. Along with the issue of not being able to rescan, I have a few notifications from people who have scanned me that do not go away when I view them, and I can’t rescan them. These issues unfortunately make it really hard to use the app since most of my friends don’t work anymore. I do love the app when it is working though!

super interesting

It’s super interesting to see what % you are with different people. It’s not always who you expect. My whole gc got on it, it was fun to see how we stacked up. It feels like the whole school got on it in two days, it was kind of insane. All my friends were checking their scores with me. My boy got a 99.5% with his gf but only a 56% with his ex. And a girl I know got her highest score with her RA lol. Idk if it’s gonna last, but right now it’s one of those world stopping things here. It’s really cool to be in it.

Literally became obsessed with this app since my friend showed it. I’m trying to get all my friends on it the only thing I would say for them to add is an option to scan out of camera roll 😭 for us long distance friends we can’t scan irl and it’s a pain having to put up the codes on another screen to add my friends. But I love this concept and I will keep using this app!
