It is hot outside but the AC is not even close to cold after driving for a while. It is somewhere between warm - cool ...

Took it to the dealer. I was told AC was re-charged ... I asked why ? Does the car have leaks ? .. was told that it was overcharged which caused leaks...

Does this make any sense to anyone ?

Maybe the tech meant to say undercharged because if the A/C were overcharged aside not feeling cold air what you will also notice the A/C compressor kicking in and out rapidly and continuously due to the out of spec refrigerant pressure within the system.

Picked up the car. The AC feels better. The invoice just states compressor/belts and all related stuff was checked. No problems found but for some reason they re-charged. Somewhat concerned what future will hold ..The interface person was gone for the day and no one really else to talk to. I dont really think they would know. My bet is they look at their data base and "if customer complains about X , do Y" type of approach at least first couple visits.

Both too little and too much refringent can cause issues. There are sensors will keep the compressor from engaging when pressure is too low or too high.

If its undercharged, you can add R1234yf if its a little low. If its overcharged, you evac and recharge. I have to make an appointment for our 21 Elite. AC doesn't get super cold, Gonna have them check whenI bring in for oil change.
