At some point in the various iOS 13 releases I feared I had lost j701 on my iPad, although the iPhone version remained ok. On the iPad, the app opened, but the special j keyboard opened in the reduced ("swipe" or quick path) size displaying only half of the full sized keys.
To trouble shoot, I checked the keyboard settings and noted that a number of them were related to an (unused) ScanPro app. On a whim, I deleted that app, and the full sized j keyboard was restored. All now seems well! What really hurts is that is in spite of a perfect 5 review rating, the app has only 1 published review and only 6 reviews. And if you look in the iPhone App Store, it is not even shown as having an iPad version. If only prospective j programmers were smart enough to install the app and use it enough to see the amazing power which the language offers... ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
