ios 14.3: working
ios 14.2: there is a bluetooth issue when using the OP-Z app with ios 14.2. the connection can be lost, sometimes after a couple of seconds. either avoid upgrading to 14.2 or use wired connection between the phone and OP–Z. note: make sure to power on OP–Z before connecting to the ios device.
