List of Android SSL MITM vulnerable apps: https://samsclass.info/128/proj/popular-ssl.htm

Highly recommend any material on the main site as well. One of the few legit infosec professors I have ever interacted with.

Heard that on an old security now episode, https://www.grc.com/sn/sn-443-notes.pdf is the best I have unfortunately, there's mention of it near the bottom there.
