I am using Inkscape. I looked online for a tutorial on how to find open paths, but my quick google did not turn up anything.
My opinion is that if they uploaded a change that breaks existing designs, they should revert back to an earlier version. I have probably dozens of designs that I’m going to have to go back and check. And some of them are pretty complex.
I’m also selling some of my designs. I test it out and make sure it works for me before I sell them. If I then sell it, and the cloud changes and the designs no longer work, then my reputation can take a big hit, since people will assume I sold them a bad design. This is a HUGE issue for me.
I understand that there may be lots of questions about open paths. I would be ok with a new warning that says “you have open paths, your print may not come out as expected”. But not with something that blocks the print completely. Especially if it worked last week.
I need to know that designs that works now will work in the future if I’m selling them to others.
