if you're experiencing the same problem as the [first pic] where: upon opening the crunchyroll app it suddenly redirects you to your settings. then, here's what you want to do.

1. delete crunchyroll (including the downloaded one on your apkpure app)
2. upon installing crunchyroll on apkpure open the version history
3. select 3.30.1

ps. if ure from the future you can download the newer version than 3.30.1 just make sure that and don't go installing the versions above 3.xx.x because those are for tvs (ex. 2.3.0~)
