Update: Spoke w/ Barclay CSR and he reviewed account. Shows 50k as "pending" and looking through activity, confirmed my purchase and AF pmt. Should have posted with 3/11 statement. They are opening a case with Rewards & Redemptions to investigate further; hope to wrap up and post by the end of this week. Trying to decide whether to apply for a third by 4/16 given this complication.
