Locked coins after character trade?

Hey guys.
Just a quick one, I completed a character trade about 2 days ago, however, if I try to gift some coins I received to a friend, it notifies me the coins are locked, please try again in 72 hours.

Now the concern here is that if I, say, wait 5 hours and try again, it still advises 72 hours. Does this just reset to 72 all the time, or is there actually progress to the lock timer, as there is no information on the exact date and time my character was traded (unless I am blind).

Have a good one.
Cheers

Anyone with some insight on this please? Currently advising me "You are eligible to send gifts of up to 0 coins, you have 42 coins."

It is likely that your sale coins are still locked from trading by the 72 hour window, and so it is telling you that 0 coins of your 42 coins are eligible for gifting.

I can't say for sure, but I imagine it is the case that the warning prompt is merely coded to display "Try again in 72 hours" regardless of how much time has passed. Your coins should still be available 72 hours after the sale date.
