I downloaded the library from https://github.com/moxiecode/plupload/archive/v2.1.9.zip, and renamed it. Previously, Drupal 7 was unable to see the library (before I uploaded the library) so I know it's seeing something, but it can't determine the version.
I'm unable to use Plupload (no option to upload images), probably due to this.

This is because this module doesn't support that specific version. There's a blurb on the module landing page that says:

Compatibility warning

Library version v2.0.0 and later are currently unsupported. Latest supported version of library is v1.5.8, which can be downloaded from https://github.com/moxiecode/plupload/archive/v1.5.8.zip.

I deleted plupload-master.zip and installed the recommended plupload-1.5.8.zip. Flushed caches and run cron.

At first the plupload warning disappeared. But the success was short-lived. And it now displaying again in admin/reports/status.
