I have just upgraded to Pro and admittedly am still fumbling around however I have run into a problem which is a completely different experience to that shown in the video for flexible content. I am unable to add sub fields unless I save them one at a time. Is this normal? If not what changes have you made that enables you to save several at a time. For me a typical experience when say making a 50/50 split row is if I make a left field and then a right without saving the left first both disappear. Any help would be appreciated especially a pointer to where I can find up to date tutorials.
