I have problems with “On Element Appear” Activity in Application written in React.
Sometimes it works as expected, another time (in same case!) with error.
It is so unpredictable.
I don’t know if your use Modern Experience, but maybe it’s worth taking a shot at using a Change App State activity, with a Wait for set to Element on Appear.
By doing that, when you indicate the target, you can easily configure a selector, a fuzzy selector and an image selector.
This dramatically increases the chances of your on appear event being identified correctly.
Even after setting this it can’t be ensured that element appears and is captured by this activity
Sometimes that element might take more than 60000 milliseconds to become active and visible
So surround that entire on element appear with a TRY CATCH activity and if any error occurs in try block then it will be caught in CATCH block where you can have the other set of activities if that element doesn’t appear
