By Juliette, 3 July, 2012 Forum iOS and iPadOS Hi, I'm just wondering if there is a way to find out the various gestures that can be used within the Zello app, as well as any key commands for the PC version. Thanks. Options Log in or register to post comments Comments Zello and messages. Hello all, I think I got some messages on Zello a few days ago, but I cannot figure out how to check them. All I can see is when the message has been sent, but when i click on the message, it does not play. Please, does anyone know how to check received messages on Zello? Is it also possible to leave a text message instead of voice message on Zello? Thank you for your help in advance.
