You can start a new thread and link to the one you wish to reference. Like you did here, but with a relevant title. Someone searching the old topic will also see your backlink. (So I suggest renaming this title to address the actual issue you’re talking about.)
If you have a solution you want to share, you can put it under Share & showcase. Or if you have further questions, you can put it under Help.
We close old topics to avoid out of date discussions as features change.
