Hello
I will tell you because I actually made an example with powerapps.
Please fix the properties of the two controls as follows.
Control Select All (pre-trip)
Onchange:
If (Radio1.Selected.Value = "yes", UpdateContext ({resetswitch: true}), UpdateContext ({resetswitch: false}))
--- Replace Radio 1 after the following IF statement with the name of Select-All control ---
Items:
["Yes", "no"]
Control PRE-AirCompressor
Default:
"Yes"
Items:
["Yes", "no"]
Reset:
Resetswitch
In my Powerapps as above, if you select Select All to be Yes, PreAircompressor will automatically become Yes.
Please let me know once again if it does not work.
Looking at the example of the screen, perhaps I think that if you reset the reset property of PRE - AirCompressor control to false to resetswitch it will work.
I hope that your work will work.
