In the last couple of updates on Ahrefs, I noticed that the UR is missing in several places. Example:
Site Explorer > Overview 2.0
Site Explorer > Backlinks
Please do not remove this metric. Many users use this metric which gives an excellent overview of a specific page's strength. I use it daily, and I hope you will add it if Overview 2.0 is supposed to replace the current version.
If it ain't broke, don't fix it! <3 :)
