Creator Mobile default value (script on load) not working

I crated a form using the desktop/online version, and wrote a script to enter the current date/time into the field on my form. When I tried loading that form on my mobile phone, it did not load the default current date/time into the field, while it did function properly when loading the form on my desktop.

Is this a known issue, or is there some way around this? Btw, I have edit available for support. The form in question is MTTS
