Zoom is ending support for 32-bit iOS devices
The Zoom software client version due for release this week will be the first that is not available for installation on 32-bit iOS devices. Among the devices affected are the iPhone 5/5C and below, iPad (4th generation and below) and iPad mini. The highest version supported on these devices will continue to be 5.11.3.
It will still be possible to launch and join meetings with these older devices for the time being, but when eventually version 5.11.3 ages out of support, their participation in Zoom meetings will no longer be possible. It is not currently known when that date might arrive.
64-bit iOS devices will continue to be supported with new Zoom software versions. In general, this includes any iOS device manufactured since 2013, but to check your device version, you can use this guide.
