KFC UK has warned customers that some menu items may not be available or packaging may "look a little different" in a post on social media last night.
Posting on Twitter, it said: "Just a heads up that across our country, there's been some disruption over the last few weeks – so things may be a little different when you next visit us.
"You might find some items aren't available or our packaging might look a little different to normal. We know it's not ideal, but we're working hard to keep things running smoothly.
"In the meantime, please be patient with our incredible teams… they're doing a brilliant job despite the disruption."
The fried chicken chain made national headlines in 2018 when transitioning between suppliers led to a shortage of chicken and gravy. Some stores were forced to operate on a limited menu while others had to close altogether.
The distribution crisis led to a 6.8% fall in sales for the group, and was one of the reasons for a dramatic drop in overall revenue to £207.4m.
