Won't Update thru OTA

I received the OTA a long time ago but just now that I feel like updating my phone because when I tried before, the update just won't install. Is it because I have TWRP as a recovery? Whenever I install the update it just leads me to TWRP, maybe that's the problem. Am I correct? If I am, how do I install the cyanogen recovery again? Without losing any data? Thank you.

Update is from 12.0-yng1tas2i3 to 12.1-YOG4PAS1N0
