Hello @eben, @moteb_marei,
To add to @Xiphware. The essentail differnce between Collect and Enketo was discussed here

Regex Problem in KoBoCollect

Dear Tinok, thanks! Yes, I can confirm this from all our tests. Even just regex(.,‘a+’) shows the difference, as KoBoCollect will only allow the sense of regex(.,’^a+$’), i.e. only an ‘a’ or word of 'a’s like ‘aaaa’ as entry. We started with regex to make sure that flexible other text entries will contain at least one alpha word of 3 letters. (Maybe instead of regex we will use the contain function.) Kind regards
