Hello, I have power apps application. Application contains orders, which admins can modify. They can modify multiply orders at the same time, e.g. Admin_1 edit order 123 and Admin_2 edit order 125. When order is modified, admins press button "Save", which saves updated information to SP list. Also on the backend when button save is pressed can be executed flow, but not always it depends on condition. Sometimes I get error 409.
My Flow (some steps don't need to understand):

1) Why I have this error?
2) How can I solve it?
Thanks
