Welcome to the community, @Ayowumie! Have you tried that on a PC to see how it behaves? In addition, please also try validating your XLSForm through this online validator to see if there are any syntax issues.
I think this is a problem specific to Kobo (and not the form) because this error appear even if i take a survey previously deployed and download and upload without any change and the errors repeat.
The problem started 10.11.2023. The same above error is produced with all my forms. @Josh@Kal_Lam
