I appreciate who answers these questions:
1- what is the meaning of learning status in bid strategy?
2- is it possible to change bid strategy in learning status from automated maximize clicks to cpc?
Learning status simply means its still in the machine learning phase and has not collected enough data yet to be able to activate your AdWords Smart Bidding Strategy.
Additionally you can hover your mouse over the speech bubble to decipher the specific reason for the learning status.
It's never too late to change your bid strategy back to CPC but this may hinder the speed at which your bid strategy learns - mostly though the factors depend on the amount of spend, conversions, clicks, and data in general.
Let me know if this answers your question!
