I’ve mentioned some suggestions below, although they’re probably already registered by @BLUEFROG somewhere and the general subject of improvements or suggestions for the DTTG actions in Shortcuts might be better off in a separate topic.
More fundamental suggestions perhaps requires a dive into the various questions that users have asked before in others topics at the time the Shortcuts actions weren’t available (i.e. the previous DTTG versions).
I couldn’t find a reference to a remark I made earlier regarding the consistency of the action design. For example the Create Item and Update Metadata actions perform a similar function, but the action uses a different layout for both. But it’s version 1 of course and these things usually require some time to mature.
Is it possible to update a sheet record in DTTG with Shortcuts?
