I have a form created with Creator that I use on my laptop and my Android device.

The form on my laptop is still working as before, but on my mobile, since a number of weeks, the form does not allow the input of decimal values anymore into an input field. The field is set up as Currency which worked perfectly before, but when I enter a decimal value and press the Submit button, I get the warning: "The number 2.5 is not allowed for this form. Only certain numbers are allowed for this field." 

So in this case, I inputted 2.5 as being a decimal. This works perfectly on my laptop, but does not on my mobile.

I have also tried to change the field from currency to decimal, but also no luck there.

The link I use to access my form is like: 

https://creator.zoho.com/user/form-name-form/form-mobile/Form_Name

When I access the link I use on my laptop ( https://creator.zoho.com/user/form-name-form/#Form:Form_Name) through my mobile browser (Opera for Mobile), I am able to input decimal values.

Since this worked before and suddenly did not anymore, I suspect a change in Zoho itself is the root cause for this.
