I talked to Barclay's customer service about four days ago. They told me they are having a problem with flight credits and they are trying to fix it. I was given a case number for four flights and was told I should see a credit in 7 to 10 days. I booked another 6 flights two days ago. We will see if I have to call again.
I use chrome and check to use points option. No problems with hotels.
