Ive also had Amazon tell me to keep it and refund the money right away. In one case, my package got lost and they sent a replacment right away. Both the lost and replacement showed up the same day and Amazon told me to keep both. The item was $105.
My paper form 4 was submitted on 7/3/19 and I got the call to pick it up this morning. Theres a thread on reddit where others who filed around that time were getting approvals. I had my fingers crossed I was in that batch.
Edit: went pending 7/3/19.
