As mentioned in the below link Built-in Rich Edit Control (TE Edit Control) is discontinued
Discontinued/Obsolete Features - - What's New (appeon.com)
We did a Test migration from 2019 R3 to 2022 R3,but the migration process doesn't report any error regrading the RTE control.we can able to save the text and also can able to retrieve the saved text without any issue.
So our concern is ,it is mentioned that it has been discontinued in 2022 R3 version.
Kindly provide the thoughts on this
Thanks,
