Dealing with unstable application

my selectors having 100% validation. (simulate) mode.
and still not working constantly stable

Im using only type into & click activities. modern version studio

It is validating fine in simulate mode as you are getting selector of the current item on display. Have a look if it has values that is somewhat dynamic, for example “order number = Order 123456” which you can then replace with “order number = Order*” the asterisk will take any other combination of order numbers so your selectors will always work

if selectors not applicable you can go with approach
