Form does not work on Microsoft Edge Windows 10

Hi there,

​I use Firefox and Microsoft Edge on Windows 10. I have a form with a master/detail form inside it and lots of blocks. After the first line is saved none of the blocks will open and you can’t save it again.

correction, I cant get this form to work on either Edge or Firefox, I cant save the form at all. Its a multiple row form, I tried a grid - this was never a problem with the old version
