App not letting me 'add notes or attachments'

I had posted this before last month but it wasn't resolved and now looks like it's been removed. 

App isn't letting me upload pic of invoices to categorised transactions, the paperclip icon appears but doesn't work. I have followed the previous instructions given, spoken with staff via the phone and ultimately was told to wait for an app update to happen. The app has been updated twice now and the problem still hasn't been resolved. 

On my previous post, other people had commented saying they were having the same problem so it is definitely an issue. 

Previous advice was basically remove the app and turn off my phone, then reinstall which didn't work. 

Temporary solution was to use a web browser but this isn't sustainable long term. 

If we could get a proper solution that would be big help.
