Find Next Marked Frame node is not working. Is it a known bug?

Of course. I’m giving frame number values in the middle of a sequence plenty of markers Actually, i’m feeding the InFrameNumber value with a Sequence player->GetCurrent Time.

Does it work for you?

Edit: I’ve made some captures. I may be doing something wrong (usually)

This function (with a coouple of PrintString nodes to confirm I’m injecting valid values, and what the node returns).

Returns this
image

In this sequence
image

(No big deal, there’s an easy workaround: I’ve added a “Current marker” variable track to the sequence and manually set each point (seen in the image). With that variable and the “Get Marked Frames” node I’ve coded my own “Find Next” and “Find previous” functions.)
