Release Date: December 11, 2025

These are the issues our team is aware of, and we are working on getting a fix out as soon as possible!

• Personalized ranges are activated when the fitter completes all the Assessment questions. If you have completed the Dynamic Movement but left some of the assessment steps blank, Personalized Ranges will not populate - fitters will see the yellow triangle alerting them to an issue.

• Several bugs related to updating your iPad to iPad OS26.

• After hitting “Complete Fit and Send Report” Fit status still shows as “In Progress”

• After Zinning a bike in the app, if you feel that the bike hasn’t been auto-leveled by the app, re-zin the wheels and trace as much as possible. This applies to all bike types except when using the MUVE SL.

• Pedal Spindle Offset

  • We are aware that users are continuing to experience issues with the Pedal Spindle Offset feature in the Fit App.

• Hardware times out after no activity

  • Sacral Sensor (AnGi) goes to sleep quickly.

    • The app cannot wake up the AnGi on its own. When you are ready to conduct a pose capture, tap or shape the device to wake it up. You will know it is awake once you see the green light flashing.

    • Make sure you have removed the thin plastic slip so the battery makes contact with the device.

  • Zin Wand

    • If the Zin Wand is not used after connecting to the app after a long period of time, the tool will disconnect.

• Issue when loading Pose Capture into the “Rider View”

  • When in Pose captures under the ”Rider” view and you go to load the right side the capture will always display double or with a high degree of error.

    • One work around that some fitters have found success with is to unload the capture and reload it.

• Unable to Generate Personalized Ranges

  • Even after completing Dynamic Movements Steps, the app is unable to generate personalized ranges.

• Client Creation: Date of Birth 

  • When you are entering the birth date for a new client, start with the birth year and then you can update the month and date. 

• Users are experiencing a Zin disconnect during their fit sessions

  • Solution:

    1. In the top-right corner of the App, tap the Vantage icon.

    2. Tap the pair option from the drop-down

    3. Wait a few seconds while observing the blue light on the Zin

    4. When the blue light starts flashing, the connection has been re-established

• Updates: Email App

  • Some fitters have reported that when they try to email a rider their fit report the email does not send from the iPad. Here are some tips to help with this:

    • Log out of the mail app and log back in.

  • We do not recommend using your personal email on the iPad being used for fits. This will avoid accidentally sending a fit report from your personal email and avoid other shop employees from seeing your personal emails.

  • In order to email your client a fit report, you will need to make sure the Email App on the iPad is set up. Please view the following PDF for email setup instructions.

  • iPad Email Setup PDF
