I'm a user of the Canvas Student app on Android. I've noticed that after updating to v6.25.1 some multiple-choice assignments fail to submit my chosen responses and instead submit a blank form with all answers marked wrong. This seemingly happens at random and seems to only occur when I submit assignments on my (Android) phone through the app and not when submitting them in a browser on desktop.
In an attempt to troubleshoot this issue, I've managed to reproduce the bug via a Free-for-Teacher account and a published quiz with unlimited attempts. Using Appium to automate submission on the student app, I recorded a blank form being submitted 5 out of 100 times the program ran. This proves that this issue isn't specific to my institution. However, I am unsure if this bug is universal among Android devices or specific to my relatively old Samsung Galaxy S7.
