Tooltip for label in not showing after upgrading to release 2021 Wave 2

We have recently applied Release 2021 Wave 2 to our MS CRM 365 instances and found that it is not showing Tooltip for the labels which we configured, isnt it strange behaviour?

Tried to find out reasong behing it and found that Microsoft has deprecated the Tooltip feature in this release with below description provided by Microsoft-

Tooltips for column descriptions on model-driven forms

With the upcoming 2021 release wave 2 (public preview in August 2021 and GA in October 2021), hover tooltips on column labels for full descriptions will be removed.

Why is this needed?

• These tooltips aren't an accessible way to access information about the column.

Impact

• Starting October 2021, these descriptions will no longer be available on hover.
• We will be introducing a new fully accessible feature for April 2022.

Hope this will help.
