Do you want to silence your WhatsApp groups forever? In the new version it will be possible, keeping the same settings as always.
Until now the options that the messaging service gives to silence contacts or groups are 8 hours, 1 week or 1 year and when the time comes (after 365 days) the notifications of the groups return again. For this reason WhatsApp in its beta version already has the option to mute the groups “forever”.
In it you can see the alternatives of 8 hours, 1 week and replacing 1 year, the option "forever".
