It is likely that Facebook is devoting all their work to the Windows 10 app. I'm happy to change the title of this issue to cover the Windows 10 app for facebook, if there are similar problems in that app.

@LeonarddeR Yes, the Facebook team is concentrated on the app for Windows 10. But its current state in regards to accessibility is not very good. The log in page is not accessible at all, it seams. If you manage to log in, you can read controls with TAB. But that is about it, based on my observations. Hope it will improve soon, but who knows...

Ideally, these issues should be reported to (and fixed by) Facebook. It may not even be possible to work around these in NVDA. I'll set to p4 in case someone wants to look into this further, though.

@supanut2000 could you test the app and give an update regarding its accessibility? Is this still as bad as before?

I have tested in NVDA 2019.1.1 with the last version of the facebook app from Windows store, the app is still very inaccessible. Edit fields are not in the tab order, you cannot jump to them with objectnavigation and you cannot move into the text etc.
cc: @josephsl I supose the priority for improving Windows 10 aps in general is very low. Right? It seems many companies just create some apps to test the Windows store but the users of Windows are not really using lots of store apps. My impression is that people using store apps are either on Android or on Apple. So I think in the future there will not be much improvement to accessibility of Windows store apps.

The Facebook App from Microsoft App store is now fully accessible, I cannot find any really significant problem with it using NVDA last alpha. I am closing as works for me. If you have individual issues with the app, please open new issues and describe them according to the issue template.
