I have a somewhat older iPad and had the WebEx Teams App working on it, but it asked me to do an update, after which it stopped working. I deleted the App, and went to the AppStore to install Teams again, and got a prompt that indeed the latest version is not compatible with my device, and had me install the latest compatible version. However, as soon as I start the App, it will say that I have to do an update, and indeed will not do anything until I hit the Update button ... at which point it stops working again. Not sure what to do here....
