Uploading file indefinitely when replacing xlsform

Hi, I’m facing some trouble when trying to upload a new version of my form. I am stuck in the “uploading file” message. The form has been previously validated using the online validator, but it still seems stuck in this stage and I am unable to continue… What could be the issue behind this? Thanks in advance.

@apvelilla, did you get any error messages when validating your XLSForm with the online validator? Maybe sharing the error message with the community would help the community to understand your issue pictorially.
