ODK Regex problem

Good morning, everyone. I’m having a problem with the ODK. When formatting a question in KoboToolbox so that a given field only receives 11 digits from 0 to 9 as an answer, I used the following regex(., ‘[1]{11}$’) expression
However, the ODK only accepts 9 numbers and not 11 as it should. Does anyone know what might be happening and how I can fix it?
Thank you,

@criscamboim, this post discussed previously should help you solve your issue:

Please note to ensure the following:

  • Your question type should be text instead of integer.
  • The appearance column should have numbers
