I am unable to add an individual tester to a build. When I attempt to submit the information, the test information is rejected because the phone number is invalid. Only numbers are allowed, the field is set to 03453131234, in fact any combination of digits is rejected,

THe problem is that the phone number must be a full international number, such +441414311234. The leading + must be present despite the statement that only numbers are allowed
