Yes, I am using the latest versions of DT Desktop and DTTG 3 on iOS. I rechecked and with this action everything works fine.
Regarding your other question: I switched to Bear. I really like to work with a nice GUI and do not need all those power action features of Drafts. In fact I have no programming skills and I never got into the whole action stuff. The “text starts here” thing never really got me either. I always write my stuff directly into OmniFocus, Fantastical, Mail and so on. Bear gives me a really nice GUI and tons of export options and a really nice pdf output.
DT is my knowledge repository, called a PKM in modern times. DT is great at storing massive amounts of data, but not so nice for creating documents like md files. I want something fast and nice for this capture step which does not get in my way and is fun to use.
With Bear (or Drafts) I gather text or pictures (not possible in Drafts as easy), flesh them out and get them out of there when ready (e.g. when the article or book I read is finished). Because, for me, neither Drafts nor Bear is good at functioning as a PKM. I export them as pdf or md to the appropriate database in DT.
I always thought this is the normal use case for DT and Drafts (hence there is this action for exporting stuff into DT). For what are you using DT and Drafts?
I am beginning with DT; I imagine basically as yours and as a Journal capture data, mainly text… I feel Drafts too less structured for acting as a Journal in itself perhaps I will try Bear
You can use the “After Success” settings on your action to assign tags and/or file away a draft after the action has successfully run. That’s probably your best bet. See:
