emacs: 29.0.50 build 7 org: 9.6-gcbe3f2 snapshot from 20220402 I use company for completion.
The issue is very simple to reproduce. Open a new .org file and input (for example) [[/home/]] and see if an auto-complete menu pops up. Do this both INSIDE your org-directory and OUTSIDE your org-directory. For me this fails inside my org-directory (at any depth within ~/org). The output of "C-h m" is: Enabled minor modes: All-The-Icons-Completion All-The-Icons-Ibuffer Async-Bytecomp-Package Auto-Composition Auto-Compression Auto-Encryption Blink-Cursor Column-Number Company Company-Posframe Diredfl-Global Display-Time Doom-Modeline Electric-Indent Electric-Pair File-Name-Shadow Flyspell Font-Lock Global-Company Global-Eldoc Global-Font-Lock Global-Tab-Line Line-Number Menu-Bar Mouse-Wheel Org-Appear Org-Bullets Org-Indent Org-Remark Org-Remark-Global-Tracking Org-Roam-Db-Autosync Override-Global Pdf-Occur-Global Prescient-Persist Projectile Rainbow-Delimiters Recentf Selectrum Selectrum-Prescient Shell-Dirtrack Show-Paren Spell-Fu Tab-Bar Tab-Line Toc-Org Tooltip Transient-Mark Visual-Line Which-Key Yas Yas-Global Notes: 1. If I try to auto-complete "/home/" without the "[[ ]]" then completion works fine.
