Toilet Seams Plus S

Hi all, has anyone come up with a solid solution to the flexing side seams on the cassette toilet on the Plus S? I know Prolite has attempted to seal and reseal without any success. The new toilet design in the 2019 model solves this issue. Has anyone had their older toilet replaced with the newer version under warranty or has Prolite come up with a more solid fix to eliminate water infiltration down the sides? Thanks in advance for all your help
