Square Invoices saying an email and/or phone number is invalid, when it is not.

Hello square team, I'm wondering if there's something we can do about this as I would love to stick with you guys. I use the invoice feature for my business, and today I had a situation where a client that I have already sent invoices to before, came in, and when I tried sending him another invoice it was now saying his email was invalid. To work around this I asked for a number, and after typing that in, it said his number was also invalid. Keep in mind, this is the second client this has happened to with me. I need to find out why this is happening and how to fix it, as i provide a service that is backed by my warranty and saved to each customers profile, so it is super important and i rely on this.

Hi @SSWR

This is strange situation I have yet to run across. Did this just seem to happen with past customers that were saved, or with new customers as well? Did both instances happen today or was today the second time?

Yesterday was with a repeating customer, and that day just decided to do that. The last time was with a new customer. They were both on separate days. What I figured out to work around this was I made a new invoice, and instead of sending It to his info automatically I put the manual option which then allowed me to collect payment, and the I sent him the invoice via link. But that did slow down the process as I had to make a whole new invoice, delete the last one, and manually send it to the client all while I had more customers waiting, so id like to figure this out to prevent it from happening again in the future
