Range Rover Sport suspension dropping overnight on one corner

Woke up this morning to find my Range Rover Sport leaning noticeably to the front passenger side, looked like a lowrider on one corner only. Started the engine and the suspension aired back up to normal height after a minute or so, but now I'm stressed that there's a leak somewhere that's only going to get worse. This is a 2017 model with the air suspension and I've owned it for about two years without any major issues, so I guess my luck was bound to run out eventually with these things. The dealer would obviously be the safest bet diagnostically but their labor rates are astronomical and I've heard the independent specialists can be just as good if you find the right one. Been searching for a Land Rover repair Sheikh Zayed Road area since that's convenient for where I work, something that won't require me to trek all the way to Al Quoz and leave the car there for days. Found Dynostar which seems to specialize in Land Rover and has the proper diagnostic system for the air suspension modules, not just a generic OBD scanner. Anyone here had a similar issue with their Range Rover where only one corner drops, and was it just a leaking air strut or something more involved like the valve block? Also curious about whether it's safe to keep driving the car while it's doing this or if I'm risking damaging the compressor by making it refill a leaking system every morning.
