Chess puzzles

As the chess puzzles do not work on my chromebook,I would like to have a go at the ones Greenpawn posts without having to use a manual board.
I know i can clear a board in analyze game and put back the required pieces in the correct places but this is a bit laborious.
Is there an easier way?

@venda

Can you let me know details of your Chromebook? Model/OS version? Puzzles should work just fine on Chrome browser unless an older unsupported version.

@Russ
It is an Acer chromebook and is quite old but I get regular updates to my system.
CB 314 series Model number N1902
Version 126.0.6478.178 (Official Build) (64-bit).
Thanks for the reply.I cleared out the cache but it made no difference.

When i first mentioned it there was one reply which said "same here"
