[DanielRyszkaIBM]

Describe the bug
We've uploaded new version of ibm-watson-machine-learning package on test PyPI - version 1.0.247
Twine upload seems to have worked correctly:

But when we try to install this version of package, we are getting error:

% pip install -i https://test.pypi.org/simple/ ibm-watson-machine-learning==1.0.247 --no-cache-dir
Looking in indexes: https://test.pypi.org/simple/
ERROR: Could not find a version that satisfies the requirement ibm-watson-machine-learning==1.0.247 (from versions: ...

I can see the package under link here: https://test.pypi.org/project/ibm-watson-machine-learning/1.0.247/
But I can't see it in simple API:

% curl -sH 'Accept-Encoding: gzip, deflate' https://test.pypi.org/simple/ibm-watson-machine-learning/ | gunzip - | grep "1.0.247"

I can see previous version though in there:

% curl -sH 'Accept-Encoding: gzip, deflate' https://test.pypi.org/simple/ibm-watson-machine-learning/ | gunzip - | grep "1.0.246"

The similar situation seems to have occured in the past with other packages based on previous issues in the repo, e.g.: #11512

Expected behavior
New version of the package should be available to install.

To Reproduce
Try to install ibm-watson-machine-learning-package in version 1.0.247.
E.g.:

pip install -i https://test.pypi.org/simple/ ibm-watson-machine-learning==1.0.247 

My Platform
I've tried it on two different platforms: Mac OS X (pip 21.2.4), RHEL

I manually purged this page from our CDN and the release is there now. Closing this as a duplicate of #12214.
