I am still on desktop, and this function does NOT work. It's very aggravating.   The field in the Customer Job has plenty of space for entering a phone number the traditional way (123) 345-7891 and for international numbers.  But for some reason now for the past few years, the Find function does not work for phone numbers. The Find field for Name Phone Number is truncated and will only take a US phone number with no punctuation or spaces.  Really QB, you need to fix this issue. I raised this a long time ago, and none of your updates ever fix these kind of bugs.
