FWIW applied last week and was auto-denied. In fact, they didn't even bother pulling my credit report.
When I received the denial letter the other day, the reason they gave was "You've reached the limit on the number of times you can have this card" or something to that effect.
I've had two Arrival cards over the past few years. Most recent was opened around 18 months ago and closed around 6 months ago.
760 score and 4/24.
