We’re having issues too using the Fiverr app on iphone IOS 14.
Messages look like they’ve sent, than when you look again at the conversation history, the message isn’t there! Then we’ve had to log into a desktop computer to send the message again, sometimes a few hours later! This has definitely lead to loss of business for us.
This isn’t every time, as 5 messages were sent in close succession prior to the one that didn’t send.
Come on Fiverr, this is a basic function of any app that can message. Yes, it works for some people/businesses, but that doesn’t mean it’s acceptable.
