RE: Metadata Regex Power Apps Portals Always matching
Hi Ethan,
Sorry for misunderstanding your issue.
I have never expericenced using web form metedata record for validation and not really familar about regex.
However, from my latest test, it seems that the field will only allow field value which match regex.
(Definition from doc: The validation error message to display if the regular expression validated fails.)
e.g: your previous regex actually will only allow numbers in first name field,
if you would like to only allow english characters, we should instead use ^[A-Za-z]+$.


After changing regex the form works.

Of course, please click "Browse website" for refreshing.
