How do I add tags when creating an expense in the iOS app?

Hi there, @Paul_R_H.
 
I can see that you've posted twice in this forum in which my colleague @jamespaul already answered your question. 
 
I just wanted to let you know that he already responded to your other post. To view his response, you can check this link: https://quickbooks.intuit.com/learn-support/en-uk/transactions/how-do-you-add-tags-when-creating-expense-entries-in-the-app/01/954566#M14290.
 
To keep the conversation streamlined and provide you with the best resolution, I'll ask that you post any follow-ups there.
