Speculation at this point:
In the Chase login it’s showing the Sapphire Reserve ‘Pay Yourself Back’ categories of Gas, Annual Fee, Select Charities at 1.25% are being extended through June 30, 2024. However, the Grocery category 1.25% is still showing the March 31 deadline which seems to indicate it’s ending soon.
For me this is a big blow as my Gas category usage is limited whereas Grocery is easy for me. You’ll want to cash out whatever you can before the 31st. Possibly purchases made today, 3/29, will show as available for cashout by Sunday, 3/31. (I don’t recall how these things settle over weekends.)
