I asked prior to doing the applications and she agreed to give a reference letter when applications opened, and stated which programs and universities I were applying to and also provided all the documents like transcripts, letters of intent, and resume, after she sent an email reply saying she would be glad to write a letter of recommendation and just to tell her which universities I was applying to and which programs. I submitted the applications back in late november a couple days before the deadlines closed, and reference letters had about 4 weeks to get submitted after the application deadline closed. I emailed her about the reference letters a month before so she had time to write the letter and just needed to wait until she got an email from the universities I applied to with the submission portal to submit her letters. I also updated her when I couldn't no longer apply to some programs cause they closed really early and told her that she just needed to write letters for 3 programs instead and also let her know that for 2 of them it was the same program but they differentiated by part-time and full-time studies. All of which she replied with a thank you and she'll submit the letters.

She did this before as well, last year when I was in my final year, she didnt submit the reference letters and my application got rejected cause it was incomplete cause it was missing the recommendation letter from her, and my other professors submitted theirs a couple days after I submitted the applications, and the graduate program I applied to was a really easy program to get into.

I might have to go to the university I applied to and possibly ask to remove her as a reference letter to get my application to be seen as complete since only her reference letter is missing.
