Restore show text frame baseline grid

[Sam A.]

In Text Frame Options > Baseline Options, I used to be able to show a Baseline Grid within the text frame. For reasons unknown to me, it has now disappeared and I fail to restore it. Any idea what has happened?

(It's not about View > Grids and Guides > Show Baseline Grid – this is working.)

Problem resolved! I played around with View threshold and then closed and restarted InDesign.
