Hi folks, this is a beta bug report not request for help.
I created a markdown file in DV; opened in BBEdit and did some writing, saved and closed in BBEdit.
The display in DV did not update to include the new text. When I opened it again in BBEdit, the text was there, but it did not refresh in DV.
I navigated away in DV and returned; still not updated.
It was eventually fixed by quitting DV and relaunching. Since then, it behaved as expected so not easily reproducible. The file is intact, there was just a glitch with the view updating.
You say you created the document in DEVONthink. That would make it an imported document by default unless you created it in an indexed group. Is that the case?
Did you try File > Update Items / Update Indexed Items ? Usually DEVONthink is pretty fast to register external changes, but otherwise that always solves it for me. I’m not using the beta though.
Works OK for me. I tried to replicate your experience as closely as I could following your description. I’m on DTP 4b2 and running Bbedit 15.1.2 (Apple Silicon). Sequoia 15.5.
