Been using this for a while now and I can say this app is very convenient. But today was terrible. I tried using it but it won't let me join a meeting. It is my second time today sharing my experience and it really frustrates me because my online class is very important. I tried turning off my phone, uninstall then install the app over and over again but it won't let me join a meeting. I don't know what to do anymore. I really hope this will be fixed. Thank you so much.
