Textastic closes the file when it's updated on server

I started using Textastic and I am loving it.

I have a problem though:

When I open a file from my pcloud server, in my computer and in my iPad (using Textastic in iPad), the text will be the same at both sides.

When I modify the text in iPad side, the computer editor updates the file's text without any problem.

When I modify the text on computer side, when the Textastic try to update the text on iPad, it closes it (closes the text).

Is there any configuration to enable such automatic update?

Thanks
