So I’m not optimistic about this getting a fix, but just in case it helps someone else, here’s my bug report and steps I’ve taken.
bug report
Problem noticed around October 2, 2022.- Browser: Firefox v105.0.3
- Userscript manager: Tampermonkey v4.18.0
- MacOS Monterey v12.6
- expected to work on wanikani review sessions
- tried both compatibility mode on and off (when it was working, comp. mode was ON)
- Description of the problem: level indicators are not appearing in additional-options area
- What I’ve already tried: run through the items listed in Sinyaven’s debugging checklist. Problem still persists after all steps tried.
Debugging steps
a) Make sure that you are looking at the right place
- review sessions → not appearing
b) Check if your userscript manager is executing the script
- confirmed script is firing
c) Are there any dependencies missing?
- no dependencies mentioned in installation instructions
d) Make sure you are using the latest version of the userscript
- checked for updates: no updates found
- uninstalled and re-installed script
e) Does the script compatibility mode affect the script?
- Setting when noticed the problem: ON
- changed compatibility mode to OFF. still experiencing problem
f) Does the problem persist if all other scripts are disabled?

g) Does the problem persist if all other browser extensions are disabled?
- all other browser extensions disabled. problem still persists
h) Check for any errors or warnings in the browser console

i) Maybe your browser’s security settings are too strict for the userscript to work
- lowered browser security settings. problem still persists
