“Improved stability. Do you have questions or issues to report?”

What are we looking for ?

My guess is if something got worse after the update that it would be good to mention it. Sometimes fixing a crash or hang, or improving performance can have unintended consequences on different hardware combinations etc.

Since I have automatic app updates activated on my iPhone I thought I was running the latest version, but it appears that I was still on 3.83.

Anyway, does the update fixes the two issues I observed this weekend?

  1. On the Galibier and the Croix de Fer, on France map, we quickly get out of the drawn map, the screen become black, and riders dots are invisible, impossible to launch a Ride On bomb
  2. Changing the FTP bias on the workout screen, then switching screen for something else like the map or riders lists or whatever… and going back to workout screen ; the bias is back at 100% even though on the main app screen at the bottom of the intervals column the right value is displayed

I don’t intend to ride those climbs soon since I’ve completed the challenge so I won’t be able to check if the same issue appears with 3.84.

I’ll try the FTP bias issue as soon as the weather forces me to ride indoor!

EDIT: Here’s an illustration of the black screen issue when crossing the “border”. After that is was all black.

I was riding Hilly Route yesterday and early in my second lap, when getting to the first route junction - right before you go up the Zwift KOM - the turn/straight arrow buttons didn’t appear properly, they were blank blue squares. I tapped one and it acted like I took a screen shot but it didn’t. Had to use my mouse to turn away from the climb and towards Ocean Blvd. iOS

I was able to reproduce this issue on Companion 3.84 yesterday
