I'm having many trouble to this app lately. first, it always says that "No internet connection" or " Waiting for network" even through my signal status is good. Second, i can't identify the user if he/she is online or offline because it says they are active a minutes ago and then when i leave a message they reply and still the "Active minutes ago" thing is still there . 3rd problem is, when i update the app i can't download filters for video calls. Please fix it.
