A lot of people were noticing points missing on their SPG business card at the beginning of April, and people worried there was some sort of crack down coming (we mentioned the issue briefly in this post). It ended up being a technical issue, and transactions since April 7th are coming through properly.
However, in the effected timeframe of March 30 through April 6, some transactions on the SPG business card are still not being credited properly, irrelevant as to where the purchases took place. The issue was initially seen on the Amex transaction beta page, and now people are continuing to see the issue even as statements close.
Worth checking that your points came through properly and opening a ticket if they haven’t. Wait for your statement to close before opening a ticket since they probably won’t take it seriously before then. Could also be that waiting another few weeks will work as the Amex gods learn about the problem and hopefully fix it system-wide eventually.

Update: Seems like this issue may be affecting some Hilton cards as well. And Amex has said in a reply via Twitter that they are working on getting a fix for this, so it might be worth just waiting this one out.
We are aware that it was just that week and have a team diligently working on this. It should be rectified by end of July. If there is another account that you think is not accurate and have viewed your statements, please let me know. ^RK
