So, the charging port on my 2018 11" iPAD pro went teats up and the unit cannot be charged. Checked it with three chargers and four different cables. Sent it to Apple for repair under AppleCare. Wonder what the usual turnaround time is, not including shipping and...buddy at a BestBuy store told me Apple doesn't really fix your unit and send it back...it puts your unit in a pile and sends you back a good "refurb" unit. Your original unit does get repaired and is shipped out later to someone who needs a refurb unit. Is this the case?
