It all takes as long as it takes. You should accept that to avoid unnecessary stress. I did mine and then Covid hit. The Embassy was shut down and foreigners were not allowed to enter the Philippines. Mine took very long because of this.
Unless something has changed, for a CR1 an appointment is sent to you. You make appointments for K1. My advice is while you wait, build your case of a bonafide relationship that she can bring that info to the interview. They are scrutinizing visa's more carefully now. Hopefully you can go visit again while waiting.
Patience is the key. Like I said it will happen when it happens and getting angry, impatient, and upset does not change that, it only makes the process worse. On the bright side, if she arrives 2 years from the date that you married, it will be converted to an IR1 which gives her an automatic 10 year green card.
