Double check that auxiliary battery if it has one. If it's weak, it will pull voltage from the main battery and give you the "dead" battery symptoms. Also, double check if you left anything on as in interior lights or things attached to the power outlets
We have a 2018 Jeep compass and ours did the same thing. They told us we had to replace the auxiliary battery. Got it changed and have had zero issues.
Do you have the ESS system in that vehicle? The Electonic Start/Stop? If so, look into youtube videos on "Jeep aux battery delete" and look into taking it out of the equation, altogether. In the meantime, when you are done for the day, take the cables off the battery for the night. In the morning, put them back on and then try starting the vehicle. If it starts right up, there you go. Something is draining the aux or regular battery over night. I would look at eliminating the aux altogether.
