Media / Light mushroom cards acting all binary

This is on an iPad. A few years old now, but “young enough” to have a Lightning connector.

Most of the time (for some reason not 100% consistently) the fader adjusters act as binary switches in lovelace. So I’ll tap or slide to turn the volume up (or down), and it wil instantly flick to 100%.

Has anyone else seen this issue?

Don’t tap them or force touch them. Touch them lightly and drag.

First thing I tried was doing it differently. No difference in outcome.
