According to the query of Xiaowo Forwarding Garden Network, Easy Sign provides multi-platform services, but it is not fully compatible with IOS 16 system.
This may be due to some functions or changes of the new system, which leads to the failure of the easy-to-sign application. If you use the IOS 16 system and need the electronic signature function, it is suggested to find another compatible electronic signature tool or wait for the easy signature update to support the new system.
