Anyway I am going to try this again with the Amex GC, this time the full $10k. My $2k purchase did not track and neither did my $100 Starbucks GC from Staples (both are now pending after I sent an email complaining and got a form-letter reply after several days).

I'm going to try a new browser in incognito mode with all add-ons disabled. Hopefully I eventually end up getting these pts...
