I have run into a strange issue. Regardless of what I open and from where, I cannot edit anything. Textastic opens the files, but it just does not respond to any keyboard input. The application itself is responsive (I can change settings, etc.), but all files are - sort of - readonly. It does not matter if those files come from external folders, are live files or “local” Textastic files. Tried restart, reinstall and did not help.
