Hi Egor Tsvetkov,
From my research into the plugin i found that assif_tiger is indeed correct, the plugin is supposed to be used only on android.
If you read the description of the plugin you may find the "iOS section" where its describes what you need to do to get this feature on iOS.
This is by not using the plugin and simply inserting a attribute in the input_field you want with name:"autocomplete" and value:"one-time-code"
My suggestion would be to use the GetPlatform action available in the CommonPlugin to assert which is the current platform and through there execute the flow you are using in the image only when on Android as to not cause the flow to get stuck when on iOS.
Best Regards,
Experts
