Pretty much what the title says. I used the app twice today and both times after roughly 15-20 minutes my entire phone froze. I couldn't do anything but my inputs were still detected, i.e. I used a shortcut to open my camera and after a while the camera opened.
I'm not sure how long my phone froze this morning but I'd say roughly 2-3 minutes. Just now it froze for a solid 5-6 minutes.
I am using a Motorola Moto g(9) power.
I didn't do anything out of the ordinary, just scrolling through the front-page, and I don't have many apps open since I always make sure to close them when I'm done using them.
I might be willing to risk another freeze, just let me know what(&how to) data to record beforehand.
