I have only recently upgraded to OS9. Was not able to update Textastic under the old OS due to compatibility issues. Therefore, I was never prompted. I'm guessing that by the time I upgraded to OS9 only Textastic 6 was available. Also, I have never synced my iPad to my desktop. I have no need to. So I guess I'm SOL. Wish I would have known about the 5.3.1 requirement before I paid for and downloaded 6.

Checked the App Store and nothing in "Updates". The app is in the "Purchased" section, however, the only option from there is to open the app. No download or update available.

Looks like I'm upgrading from 5.1.1. Don't see a 5.3.1 upgrade available anymore. Anything I can do to remedy
