I noticed this recently too, @zola_mzimba – I cannot access Google Drive anymore.
The thing is, it’s not actually Airtable’s problem, nor can they directly fix any issues in that interface, because that interface is actually another app called Filepicker. Airtable is only using their API inside their iOS app, presumably so that they don’t have to write their own file-selection functionality.
However, Filepicker.io appears to have gone defunct, and possibly been purchased/supplanted by filestack.com, because Filepickers root domain now redirects there!!
I have a feeling Dropbox and Google dropped support for Filepicker.io due to it’s defunct status. Airtable really needs to either switch over to using filestack’s API, or else build their own file-selection functionality – it’s long overdue, really.
Sadly, I don’t see a good solution to your problem, except maybe to try and see if you can somehow save your PDF’s to your camera roll. This will probably convert them to JPEG’s, but at least you’d be able to access them from Airtable’s filepicker interface. I’m not sure of all the ways you could go about saving a PDF to your camera roll, but I know I’ve done it with an App called Scanner Pro on my iPhone.
