ERROR IN VIEWS: We are unable to fetch this data, sorry. PLEASE HELP

When I’m trying to access most of the views of the App mx-netdev I’m getting this error:

We are unable to fetch this data, sorry! Please note that your data is SAFE.
Report this problem to support@.......

Already report that to support@ but no answer yet.

This is happening in most of the views, actually, in all views linked to the form Leads_Form

The app is already shared to support.

Please, I need this to be fix ASAP since it’s creating me a huge problem during the downtime

Thanks
