"Back-button for tactics trainer?

It would be helpful if there was a back-button for tactics trainer because my brain doesn't always remember the logic to a move once it is "solved."   On my worst days I might not even remember where the original pieces were placed.  Currently, once the problem is solved the only option is to move forward to the new problem.

Thanks!

I have asked for this for years.

Isn’t there an analysis button

Thanks, cellomaster8!  That certainly helps.  Not as easy as a back button, but at least it's an option for reviewing the problem.

Thanks again!

You’re welcome

@Hindu Lover is the following:

This guy is a well known troll.

    He always does the same thing. Lowers his rating to ridiculously low(200-500) , then plays a perfect game  and asks stupid question , pretending that he doesn't know how he won. Then he posts more stupid questions , usually with openings that clearly blunder and he pretends that he doesn't understand if they are good or not.He always asks stupid questions  like "what is tempo?" " what is en passant?"  "what is castling?"  and if you answer more stupid question will follow(like "what is material , can I cook it?")

    Check his games and you will find a lot of them resigned in the first moves , even in winning positions. He is a sandbagger(cheater) and an idiot with serious inferiority complex. All his previous accounts were reported and banned but he always opens a new one.

    Don't bother!

Ah I see you’ve been working on your responses see to this infamous paragraph(s)! Well done.

He is reported.

Update:  Apparently there IS a back-button on the desktop version.  As previously noted, cell phone users can replay via the analysis button.

Thanks again!
