We have tested and found no issues with POD Express, Catalyst, Spider Remote, AMPLIFi, Firehawk and Mobile POD applications on iOS 17.5.1 [iPhone 11 or better] and iOS 17.5.1 [iPad M1 or better].
Sonic Port works on iOS 17.5.1 [iPhone 11], but is untested on iOS 17.5.1 [iPad M1] (although we expect it to work). Sonic Port VX works on iOS 17.5.1 [iPhone 11] and iOS 17.5.1 [iPad M1].
Also, please note that a Lightning-USB-C adapter is needed for using POD Express with POD Express Edit. We suggest using an Apple-branded adapter for best results.
