Any phonenumber is wrong…..

Hy, any phonenumber entered in the reservation-form, results in the errormessage:

“Please enter a valid phone number where we can reach you.”

We tried any combination with and without “-“, spaces and no spaces, mobile numbers and so on. We alsways get these error!

Maybe it’s becaus ewe upgrades on WP 5.2?

Thank you for your support.
