Amazon ordered canceled

I ordered a horned dragon yarn bowl Feb 16th and it was shipped Feb 18th. I got up this morning to an email stating that the order was canceled. The email also states I'll get a full refund. I didn't cancel the order and it doesnt state that the seller canceled either. It shows on my account that its still in transit and will arrive Feb 23rd-25th. Should I reach out to Amazon and see whats going on or just let it go and see what happens?
