iPad stuck in guided access mode.
I have an iPad pro that was placed in guided access mode for an event, connected to the event wifi. Now need to change the wifi connection. However, when I try to exit guided access by triple clicking the power button (there is no home button) it tries to enable voice control instead and asks to download files. I can't find any way to exit the mode. Also tried connecting to my Mac, but a running Catalina so can't download the latest software to link to the iPad. Any ideas? Thanks!
