I work from a smartphone. The smartphone is connected to the router via WiFi. I add the "registration" of my smartphone to the Access list. This is where the problem begins. I can't edit this access list. Every time after making changes to the Access List, the WiFi connection is broken and the changes made are reset before the apply button is pressed!
Smartphone Honor 9x pro (Model STK-LX1)
Mikrotik hAP ac2, RouterOS 6.48.3
Mobile app Mikrotik Pro v1.2.19

Работаю со смартфона. Смартфон подключен к роутеру по WiFi. Добавляю "регистрацию" моего смартфона в Access list. Тут начинается проблема. Редактировать этот access list не могу. Каждый раз после внесения изменений в Access List рвется соединение WiFi и внесенные изменения сбрасываются, до того как нажата кнопка применить!

This is true for all configuration methods. Changes to access list will restart the wifi interface. Do this only from a wired connection, or simply be aware of this limitation

Understand that wifi interface will restart, but why is changes not applied?

That should not be true. Maybe he tried to apply several changes, and that is why connection broke after first change

Can be, will have to wait for OP to clarify, but to quote OP:

I'm changing one parameter "AP Tx Limit"
The Wifi is turned off, and then the application is closed. Disabling WiFi is performed immediately after making a change to the parameter. And my intuition tells me that you should first click the apply button!

That should not happen, create a support ticket by sending details to support@mikrotik.com
