I am able to view "Read by in particular 2 groups

Question

Hi

The setting is On and I am able to view "Read by" in 3-4 groups but not in particular 2 groups.

So need to know If there is any setting can be done on particular Group chat.

Answer 1

How many members are in these 2 groups? Just note that the Read by option shows who’s seen your message only in a group chat of 20 people or fewer.
