I put template in the post. I actually put the usual talk page (another no-Flow forum). But content in this post not updating - in the talk page constantly creating new topics, but post show like an old revision that talk. I tried add to the topic URL ?action=purge - it did not help.
I edit content of post as "null edit", but it is recorded as a new revision. https://ru.wikipedia.org/w/index.php?title=%D0%A2%D0%B5%D0%BC%D0%B0:Selr9nu2y6llspcp&action=compare-post-revisions&topic_newRevision=sen2gc43fonfq2lb
Flow should draw and update templates as it is done normal pages.
