On certain topics, once the topic loads, if you start scrollng down (or even if you don’t), the number showing which post you’re reading in the topic tomeline is not there, and only loads after a while (so the timeline looks like ‘/13’ instead of ‘3/13’.
This happens on topics long and short, and on mobile.
Apologies, perhaps I should clarify. Normally, when entering the topic, the topic timeline would show the current post. However, it’s blank and only appears after some time.
I will try to get a screenshot the next time I see it.
