What's New in ONX

8.802.0

September 8, 2026

This release is mostly us cleaning up after ourselves — a liability waiver that wasn't displaying properly, plus a few other things we've quietly tightened up behind the scenes. Quiet progress, delivered with a little humility.

Last update messed something up

As of six days ago, the app is mostly useless. The update was supposed to improve stability and loading times, and both are now significantly worse. 75% of the time the app now gets stuck on the loading screen. About 15% of the time the app crashes after being stuck on the loading screen for several minutes. About 10% of the time, if you wait 5+ minutes the app will successfully load.

Hopefully it gets fixed soon because the app is lot more convenient than going through the mobile website.
