Answer 1

Hi Kastle,

I'm Ramesh, here to answer your query at the Microsoft Community.

File Picker UI host (pickerhost.exe) shows the Open/Save as dialogs in Store apps.

Please check if the same error appears in any other Store app. For example, see if the error occurs when taking a snip using the Snipping Tool (Win + Shift + S) and saving the image from the Snipping Tool. That way, we can determine if the problem is with pickerhost.exe or the WhatsApp app.

Answer 2

Hi there - it was supported on previous versions?

Answer 4

Hi, recently it worked on its own and the issue was resolved.

At the time no document could be uploaded from Whatsapp.
