I just loaded an amex card that had $312 on it to Venmo. AMEX secure pay card so be exact (I'm new to this so not sure if these are treated differently than other amex gift cards). Bought Yesterday.
Sent $312 immediately to a relative where it went through smooth without any 3% fee added. Went on to check the balance online and everything looks normal. Tempted to go buy the $3k amex gift card and unload that. Others still having troubles?
Also, did not even get the 3% red fee sign that others have said they see.
