Sorry to hear you are still having issues. Your pedal and H90 Control versions are both up to date, there is no update necessary.

I do not understand how there is no update icon displayed in the app, this will alway be there, although it may be greyed out if the device is unavailable.

I would be helpful to share a screenshot of what your H90 Control landing page looks like. Please respond to your support ticket with a screenshot and we can go from there.
