We’ve discovered a game bug that removed the option to select ERG mode from the Workout menu on all computers (PC and Mac) used as a platform for Zwift. Sorry about that!
We’re not collecting any additional information on the bug at this time, but we expect to have a fix in the next game update, which we’re aiming to send out very soon.
The good news is that ERG mode still works and I’ve personally tested it to confirm that fact. If you have a smart trainer paired to the game when you start a workout, ERG mode should automatically be turned on by default.
If for any reason you feel that ERG mode is not turned on, you can toggle ERG mode on or off from the Zwift action bar during your rides, or from the Zwift Companion app.
I’ve included screenshots displaying where you can find the ERG mode buttons on both the Zwift Companion and the action bar in-game on your computer.
If for any reason you feel that ERG mode is still not working even after your attempts to toggle it on as described above,please submit a support ticket
and one of our Zwift support colleagues will be happy to assist you.
