Since you quoted part of my post you were directing your criticism to me.
I do understand the frustration many have had with Princess customer service & the app. OP has my sympathy.
Many have offered their time , support & advice in two similar threads from OP.
No need to keep this going.
Well, congratulations on accomplishing your task.
I learned to only ask for one thing to be done at a time. The experienced agents seemed to have been let go or quit when the pandemic took over our lives.
