Dear Support Team . We have an iOS application(link - https://apps.apple.com/us/app/vlume/id1325346984), which is written in React-Native. We using also an UI Automation Tests (Appium XCUITest). Could you please help us to understand why XCUITest has a big delay for each call from Appium side

1. find element 1-3min per command
2. click element after finding 1-2min per command The same tests are working on Android 5 times faster We use:
3. Appium - 1.17.0
4. Xcode - 11.3
5. iOS - 13.3.1 , 12.4.4
6. Real devices - iPhone 7, 6s, 5s
