Can't turn off guided access
We have a 7th Gen iPad running iOS 15.6.1. Guided access has been set up on the iPad. I'm trying to turn guided access off, but triple clicking the home button isn't working (specifically nothing is happening) . A restart and/or power off isn't working as I get the message 'guided access enabled, triple click home key to turn off'. I've tried triple clicking the home button, triple clicking the side button (as this is mentioned in some posts I've seen about this issue) and I have tried to power the device off. I just keep getting the msg about guided access being enabled and to triple click the home button to turn off. Triple clicking isn't working. Please can you help
