I work almost exclusively on an iPad Pro. iOS 13 uses the desktop version of Safari by default — so it should be the same as working on a laptop. However, when I try to adjust the column width of a table on my iPad (by touch or using a mouse), it is difficult to do in Infinity. I suspect this has something to do with the touch interface. Holding on the cell produces a contextual menu with options. Now and then the blue line will become visible before the contextual menu. When that happens, I can sometimes adjust the column width — but that happens less than one time out of ten.
I hope you guys can look at this. This doesn’t happen to me with AirTable. I can see how Infinity is (or will be) so much more powerful than AirTable — but sometimes little issues like this one make such a difference in daily use.
