The PG Desktop app is pinned to use PhoneGap CLI 6.3.1 which in turned is pinned to use connect-phonegap 0.23.1 which is missing the gap: entry from the Content Security Policy. Without this entry the communication between the native and JS side is broken as iOS will not allow the connection.
This was fixed in connect-phonegap 0.23.2 and included in Phonegap 6.3.4.
