Do you have a specific date or will we get a notification once update is done and files are ready to view on the old Plain Text app?
Thanks
So I edited the same file in OS X 10.7.5 (Lion) using TextEdit, saved but still no luck. But a new file created in OS X, with the contents copy pasted from the "unreadable" file was readable in PlainText. Could the problem be PlainText cannot read ASCII files created in Windows? All this was done in Dropbox.
Also Dropbox synchronisation was pretty poor, only uninstalling PlainText and downloading again from Apps store sorted this out.
It's frustrating to see a reliable app I've been using for a while deteriorate so much!
