Flickr - how to downrev mobile app to something useful

Just this week Flickr updated their Android mobile app.  It's what I use when on the road. The latest version, v5, however, is half baked and lack functions I rely on.  The new version does not (yet?) ...

• Allow image selections that then upload through Flickrs app
• Name multiple images on import
• Add images to groups from the uploader
• Tag multiple images on import 

The v5 app is very clumsy and forces a user to deal with one image at a time for naming, tagging, and group submissions.

Frustration breeds solutions, but only after I calm down.  Here's one way to downrev the Flickr mobile Android app to the last known good state.

• Uninstall Flickr
• Download the last known good version - I use APKmirror
• Go to Play Store and install APKmirror Installer
• Run APKmirror Installer 
• Select the older Flickr version 
• Follow the directions
• Go to PlayStore - settings - manage and disable Flickr auto-update

I've left out certain details as I'm typing this on a mobile device. But this is a decent outline of how to get around Flickrs latest mobile app version deficiencies. 

 If further clarification is useful,  let me know and I will update this when I get in Big Computer range.
