It’s there, Same here at first did not see the fly more combo for Mini 3 Pro on DJI site.
Keep Strolling down, took me a second order to find it. Originally, just ordered the mini 3 Pro with SC, with two year warranty. Wasn’t until a second pass, seen the flymore combo and ordered it on the second order.
Hopefully, they send both packages together, if not I’ll be receiving two packages.
If you’ve already placed an order, just create another and select the Pro/SC combo, select one or two year warranty, select the fly more combo, then at checkout ease everything but the fly more combo. That’s what I had to do at the to create another order minus the drone and warranty.
You may need to go back to the previous page to see the fly more combo, but that’s okay check out will still retain what you ordered. Just readjust the order at checkout plus/minus .
Good luck,
