Zoho Forms that worked before are now blocked behind a paywall!

Since today my Zoho Forms that have been used every day for the past year are blocked from use because they use a subform and advanced fields. Simply because it is now a premium function instead of a free one!
I was not even warned in advance causing me to run into this major issue without warning.

First the Invoice/billing system not supporting XML, now shifting functions from free to paid without any communication!
is it Zoho's intention to hurt their clients??!
