Need webdav and can’t save files – Texifier : LaTeX editor Review

This app is great on macos but not complete on ios. Currently this app can’t be used for work because of the following issues: 1. Can’t sync with 3rd party cloud services I can’t link a folder using the files.app within the app. No webdav support. 2. Sometimes can’t save files This is the main reason that stops me using this app for working. Although it can link some third party files from some webdav cloud services. After typing 2 hours, when I want save the files, I have to close the editor, there is no “save” button. Although it says that it is “saving”, when I open the file again, I found that I lose all the content I’ve typed for last 2 hours and that’s really terrible. The file system is not stable. I hope this app can have better file system and I really want to use it since its latex support is great. And currently I’m using some code editor on ios like textastic to type latex which can save and sync files.
