Reviewing Old Tactics

Sometimes I do Puzzles (Tactics).

Sometimes I make comments on those Puzzles (Tactics).

Sometimes my comments are actually useful/helpful.

When someone else makes a comment on a particular puzzle (tactic) I get an alert.  In that case I go read their comment.  I used to refresh my memory as to what the puzzle (tactic) was by stepping through the solution, but it seems that one can no longer do that.  I only see the beginning state of the puzzle (tactic).  I'm not smart enough to remember the solution...especially for those that I failed.

Am I doing something wrong or is this the way things are these days?

Thanks, ###.

Is there not a solve button? I guess it won't let you redo the same tactic, but if you to engine analysis  you might find the mate. Also, there should be a show solution  button if there isn't  one already.

First, I should mention, I'm on the free plan.  Perhaps, that makes a difference.

Second, no, there is not a solve button (except for the "Solve Puzzles" button which is to do more puzzles).

The buttons on my screen are left & right arrows (grayed-out & inoperable), download, share, comments, select mode, and settings.
