Hi folks,

I have a flow where I ask the user for a PDF file. I am using a User Input field that saves the URL of the uploaded file to a custom field. That works great. However, Messenger on Android doesn't offer an option to select documents from its internal storage, the only offered option is to select images. Different to the desktop versions of Messenger, which have an icon to upload documents (any type), next to the chat text field. My solution is to instruct the user about selecting the PDF file from the internal storage (not from Messenger) and Share it to Messenger / Chat. That way, the bot in Manychat can receive it and works fine.

To show this message only to users on Android devices, I would need to determine if the user is chatting on an Android phone. Anyone has had this need? Any native recommendations?
