Try this
- Look for the exact text, time and status in the intended conversation. Use the app’s supported retry action if it clearly refers to the same message.
- If status remains unknown, wait or ask through an appropriate channel before sending a second full copy.
A worked example
“I’m unsure whether that message went through. I’ll check its status instead of pasting it again.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
A network failure does not by itself prove non-delivery. Keep unknown separate from failed, and avoid claiming that the recipient has read an item merely because it was accepted by a server.
