GROUP READ RECEIPTS

Telegram v8.1.1.0 (and newer) provides group read receipts feature.

Do the following to see who has seen your message:
1. Tap on a message.
2. Tap on a first item in menu which appears (see. screenshot).

⚠️ Please note the following:
1. You can see who has seen message only if it was sent to group and if that group is tiny enough. Reportedly group should have less than 100 members.
2. You can see who has seen message only for your messages (sent by you).
3. Readers list is stored only for 7 days.
