I can confirm, I received $300 RP on an item bought using a gold AU on Schwab Plat account.
Also, a note about going over the $1K on a different card.
In the past I would receive a notice saying something on the order of sorry you are only receiving x of y back due to exceeding $1K.
This time I simply receive a message back saying we are pleased to let you know you are receiving x dollars back, with no explanation.
They are also way off. I was over by $20, but they only gave me $9 back on a $163 item, and $40 back on a $45 claim sent in on the same day.
It makes no sense.
To further complicate this, this is on a account where I had a $300 order date for 12/30/20 but charge date of 1/3/21. So I wasn't sure where that order hit, if it hit my 2020 allotment or 2021.
I had tested this earlier by making a charge that would exceed $1K if the $300 was in 2021. This test claim came back fully paid via RP. So it indicated the 12/30/20 order did in fact hit my 2020 instead of 2021 allotment.
Anyway, what they paid this time on this account makes no sense. If they had gone back this time and thought the 12/30/20 order was for 2021 then I should have received nothing because I already had been over.
It just shows to me, this is something of a manual process, and I think they messed up the calculation since it went over $1k.
