Until (very) recently iOS users saw the same thing you did, e.g. the text describing the reaction instead of the reaction itself. The person sending the reaction sees it on the message like an iMessage, but everything in a non-iMessage group text (iOS, android, or other) gets sent the same “liked your message” text. Nowadays both Android and iOS parse those texts and apply the reaction as if it was sent normally, but that’s a decent change
