Question Im confused with php version on my ionos server

[rsflorendo]

I already change my php version in plesk from 7.1 to 7.2. But when I login using SSH, I found that the php still 7.1


I logon to root and followed this link >>How to specify command line command "php" version for SSH user on the Plesk server?

It works fine.

But when I logon sss on subdoman_user, the php version still remain 7.1.

How to upgrade my subdomain?

Please help.
