Dear user, Thank you for the feedback.
To check your message status -
√ = not delivered
√√ = delivered
o = read
! = network issue
If you see 1 check (√) or a red (!), change your network. A VPN may help.
If messages show 1 check (√) and calls say “your buddy is not online,” you’re likely blocked.
Best Regards!
