We have not observed such problem on our end, plus there are other workarounds other than the plugin which you can try.
If you wish to stick with the plugin, you can debug directly on your iOS device using the built-in debugger, for more info see Debug on Device
help article. You can also install and use Fiddler
to intercept your device's traffic and give you a clue what's going on by reviewing the requests/responses.
