InvalidSelectorException

Hi
Recently updated my Appium and Pycharm
we are using Appium with Robot Framework for mobile app testing
Previous my robot script was working fine.
But recently we are getting error “InvalidSelectorException: Message: Locator Strategy ‘css selector’ is not supported for this session”

Let me know if need further information on this issue

Robot framework should ideally work if it uses Appium but then Appium Studio hasn’t been verified and tested for the same.
