SMB connections in the Files app have been very unreliable for me in the past.

It works fine immediately after connecting to an SMB server, but as soon as it gets disconnected, it won't reconnect reliably. You need to recreate the SMB connection in the Files app and add it to Textastic again to make it work again when it is in this state. This is something out of my control that Apple has to fix.

I wouldn't recommend using SMB shares with the Files app. I have seen the problem you are describing as well as hangs when using the iOS Files app's built-in SMB client (not related to Textastic, reproducible in other apps like iA Writer). Instead, I recommend to use Textastic's built-in SFTP client:

If you need live editing, I can recommend the app "Secure ShellFish" which allows you to connect to SFTP servers from the Files app and works great with the external folder feature of Textastic (the app's "Pro Unlock" is required for uploading changes):

You’re welcome. Just let me know if you have any other questions. 

Hello,

when you cancel the subscription and the trial expires after one week, you should be able to get the one-time purchase of Textastic Pro. In Textastic, go to Settings -> Textastic Pro and you should either see the paywall or your current subscription status.

This is fixed in Textastic 10.8.3, which was just released.

This was fixed in libcurl and will be fixed in the next update of Textastic.

Ah, yes, that would be great...

Which select/cursor bug do you mean?

Another customer also reported this problem and I could finally reproduce it on iPadOS 26.1 beta 3. 

The issue should be fixed in Textastic 10.8.2 which was released today.

Textastic uses libcurl for SFTP downloads. 

This looks like a bug in curl - I could reproduce it using the curl command line tool. 

I reported this issue at https://github.com/curl/curl/issues/19165
