Subscribing to Oracle Learning Subscription seems good in theory but bad in reality.
Oracle support informed. “Oracle University’s policy regarding Learning Subscription courseware materials is that they cannot be downloaded by customers.”
How convenience of Oracle as the info should have been stated at https://education.oracle.com/oracle-learning-subscriptions
Took for granted materials can be downloaded since they are made available to download for all other training formats.
This seems to be a deceptive process by not disclosing the information. because by the time one has subscribe to find the lack of full disclosure, it may be too late.
Hopefully, this will help anyone to avoid the same mistake.
