Can't share markdown file to other apps

DEVONthink To Go

In DTTG v4, create a markdown file.

Long press and click the Apple share icon, to open the file in an app of choice.

Clicking either iA Writer, Ulysses, Journal, iwriter pro, does not open the file in those apps.

Is this a bug in iOS?

The same here, but only on the iPhone. On the iPad it works like expected.

I remember some issues with share sheet not related to DTTG. A device restart (yes, like in Windows) should solve it.

Unfortunately I’ve restarted my device (iPhone 15) but the problem still persists.
