What does a question mark in a square mean in WhatsApp messages - in detail?
A square-enclosed question mark in WhatsApp messages is a visual indicator that the message has not been delivered successfully. When you send a message on WhatsApp, it typically changes from an outline to a checkmark once it's sent, then to two checkmarks when the recipient receives it. If there's a problem with delivery or if the recipient's phone is offline, you might see this square-enclosed question mark.
This symbol signifies that WhatsApp has attempted to deliver your message but has failed to do so successfully. The reasons for this can vary. It could be due to network issues on either end, the recipient having their phone turned off or in airplane mode, or even a problem with the WhatsApp servers themselves.
If you see this square-enclosed question mark, it means that your message has not reached its intended destination and might need further attention. You can try sending the message again after some time to see if the issue resolves itself. If the problem persists, checking your internet connection or ensuring that the recipient's phone is online could help resolve the delivery failure.
