Vexes on the bedrock version are slow and it takes most of the challenge out of fighting an evoker. This has been in the game for quite a few updates now and I've been patiently waiting for it to be fixed.

Thank you for your report! However, this issue has already been reported as MCPE-41879. Also, this seems to be WAI (working as intended but don’t quote me on that.) However further testing is needed. Have a great day! 🙂
