Broke the third-party keyboard!!

This might sound bizarre. But here goes...

I noticed that my third-party keyboard (I use Gboard) stopped working! Changing the setting (to allow third-party keyboards) within this app didnt help as Gboard continued to hang and not show up for use in any app - be it Messages, or Mail, etc.

I was therefore forced to uninstall Documents (which otherwise seemed promising). That said however, Im still unable to use any third-party keyboard app on my iPhone... Fairly sure this has something to do with Documents and I hope a fix is released.

On another note, has anyone else faced this issue? Any recommendations? Thanks in advance - @lord_kartz (twitter).
