Since i've known Coinbase they had the PayPal option, keep in mind the FEE is 3.99% (same as using the credit/debit card) ALSO and very important - your info on Coinbase has to be identical as in PayPal - what does that mean? I think (you have to double check though) that login email should be same as your login email at Paypal.
Also, I read somewhere that PayPal is a little sensitive about Bitcoin and crypto in general (but that might be BUYING BTC with PayPal, not depositing $$ into Paypal) - still research before using PayPal option is best IMO.
