I am trying to reply to https://support.shaw.ca/t5/tv-discussions/sound-not-syncing-with-picture/td-p/4449 and it keeps failing with "Sorry, unable to complete the action you requested.", yet I can reply to this post.
It seems I can reply to that thread if I try to reply to something on page 1 but all other pages are giving the error.
There is another discussion thread on this forum that has reported the same issue.
It used to work, until some administrator "upgraded" this forum's software. Sigh.
