Premiere Pro not allowing slow motion in timeline

Hi! I was having this same problem (8 years later) and read through this entire thread and tried the "Modify->interpret footage" in the project panel, and when I dropped the footage in, it does not work. What should I be doing these days? I have version 23.1.0/Premiere 2023

and make sure when dropping your 120fps to the 23.976 sequence, if a message pops up asking whether

you wanna keep the sequence settings or change them to match the clip, choose keep settings (keep them at 23.976)

You may need to go to the clips, preferably in a bin before putting them on a sequence,  right-click and Modify/ Interpret Media or whatever the exact wording is, and give it the frame-rate you wish it to be shown as.

Once on a timeline you would need to select the clip or clips and do the same thing. Remember that you can select multiple clips at once.

Can you please send screenshots of your sequence settings after dropping the 120fps footage into the timeline ?

Can you share screenshots of your export settings ? especially the frame rate settings under Video ?
