I found this previous feature really helpful as it helped me narrow down which posts are the best to read for guidance & tips. 
i think they’re fixing it momentarily
I noticed that as well. I thought it was because the forum will be more about conversations and less about problems and answers.
Ah, thank you for your insights! 
Is there someone we could ask or tag, to confirm?
Community Manager is still working on stuff, for example you should see that you can now mark posts as solution again
@ILM - Ah yes, I can see that now. Do you know if the historical replies marked as solutions will be available for folks to see after the updates?
I don’t know, it could be they have been lost when the feature was turned off
