Seeing some Sale History Gil discrepancy with retainers with the companion app:


Compared to in-game accurate Gil amount:



...It seems like the companion app multiplies the Gil amount for each item (after taxes have been removed) another time.

Such as the Glamour Prisms being sold for 1162 Gil each, but then get multiplied again by the item amount 562,914 from:

1162 * 22 * 22 = 562,892... close enough to 562,914.
