I used to be able to access the Apparatus for the Greek New Testament: SBL Edition from within The Lexham Greek-English Interlinear New Testament: SBL Edition via apparatus markers.
I cannot see the apparatus markers within The Lexham Greek-English Interlinear New Testament: SBL Edition anymore. Has there been a change?

Lexham Greek-English Interlinear New Testament: SBL Edition. This is an interlinear version of the SBL Greek New Testament. It has the same type of data as the existing NA27-based Lexham Greek-English Interlinear New Testament (lemmas, morph, transliterations, Louw-Nida references, Strongs, and two levels of English glossing), only it is an interlinear of the SBLGNT text. It also includes apparatus markers, which are linked to the SBLGNT apparatus. Thanks to Hall Harris for his work in getting out this edition of the interlinear. (emphasis mine)
