Thanks a lot for sending me your syntax definition. 

I could reproduce and fix the problem. It was an issue with "embed" operations.

This should be fixed in the new beta I just released.

Can you please send me your custom HTML syntax highlighting as a .zip file so I can try to reproduce the issue?

So, is this a new bug or did this happen before the latest beta, too?

I can see your crash in App Store Connect / TestFlight. In fact, I see several from you also from past TestFlight versions. Unfortunately, there seems to be no crash details attached.

Do you have any customizations in the "Local Files/#Textastic" folder?

Can you send me a screen recording of the hang and crash? Maybe it helps me reproduce the issue.

Hello,

it works fine on my devices, so can you please answer some questions?

• How exactly are you opening the HTML file? Where is the file stored? 
• Which theme are you using?
• Can you send me the file that causes the crash? 

Thanks!

I've been bitten by this behaviour myself. I think I'll change it so that auto indentation is not applied to the last line when pasting multiple lines of code.

Hello,

thanks for the report. I can reproduce the problem. I see the same issue in Runestone Text Editor, which uses the same UITextInteraction API as Textastic.

As a workaround, tapping on the insertion point (sometimes twice) brings up the Paste menu for me while long pressing does not seem to bring up the menu.

You can go to Settings -> Other and tap "Reload Customizations" to reload code completion files, syntax definitions and themes without quitting the app.

Alternatively, you can use Cmd-Shift-R on an external keyboard to reload customizations.

This is explained in the manual at https://www.textasticapp.com/v10/manual/customization/custom_syntax_themes_templates.html#reload-customizations

To use the built-in code completions in case something doesn't work anymore, you can just delete your custom code completion file and reload customizations.
