Default Front differential oil level

Hello. Bert here. The car in question is a 2013 Crosstrek with CVT.
I have searched this forum and youtube videos til I'm dizzy, and can't find a simple answer.
The video I found didn't give an amount, they just filled til it overflowed. That makes the most sense to me, but I've never had a Subaru before.
What came out appears to be probably less than a quart. I now have darn near 2 quarts in there, and no overflow is evident.
Now I read that there may be another plug somewhere that is the proper fill level.
Is this the right hole?

Thanks for your time.

My Vehicle: 2014 XV Crosstrek MT

Hey Bert, I have a MT that is set up differently but according to the my PDF service download, that looks exactly like the fill hole for the front diff with the CVT. The PDF specifies 1.4-1.5 US quarts so I wouldn't look for any to be overflowing.
good luck.

Wow What an anemic tech forum this is.
Disappointed here.
For anybody here that actually has the nerve to do your own maintenance, The answer is a simple one.
On the bottom of the diff, close to the drain plug is another smaller plug that I'll call the "overflow plug". This plug leads to a channel that is open up to the proper level of oil in the diff. when you refill, put the drain plug back in, but leave out the overflow plug. Next, Pour oil into the fill hole on the right side of the diff (pictured above) slowly until some oil runs out the overflow hole. Put your filler plug and your overflow plug back in place, and you're done.
Or, you can let the dealership do it for you and loot your wallet. Suit yourself.
