Support › Meta Box Columns › Bootstrap
After the last update, the fields stopped respecting the bootstrap when used on cell phones and tablets.
I disabled all plugins and enabled the default theme.
In this first field "Diário de obras", there are 3 fields, the first with size 6, the second 3 and the third 3. See that the line has not broken. There was not one field under the other.
Thank you for your feedback.
I've informed the development team to fix this issue in the next update.
