I am on the current Office 365 channel, but manually check for updates. On one system, after installing the latest 2403 build, no recent docs show up in the file tab on all Office 365 apps, nor would newly opened files populate. These are all local files (home computer). On another computer with the same Office build, the issue does not manifest. Performing a repair uninstalled office. When I reinstalled from my account portal, 2402 was downloaded and recent files populated correctly again in all apps except Word > For all other apps, the recent files that had disappeared returned (so the file that contains the recents was clearly intact and readable). For Word, recent files functionality worked again with 2402, but it was starting from scratch (all previous recents were gone, but new files populated.) Something in the 2403 build of Word is mucking with recent files for all Office apps (at least that's my hypothesis). My concern is that when 2403 is pushed/forced, I will have to live with the issue.
