I check in early to my hotel quite often. I don't use the online check in on those times but I am very nice to the front desk person. I say that I realize I'm early but hoping they had a room ready for me. At that time, they usually ask about digital key and if they don't, you can always mention it or request it through the app later. It usually doesn't take long to be delivered to your phone. so you can use the key card to first get in (if you have to) and then use the digital key the rest of the time. Sometimes I purposely get a key card as well b/c I haven't had much luck with the digital key opening outside doors or pool areas at some properties.
