UPDATE (17 Apr 2020, 15:00 BST)
The updated version of the extension (v. 8.32.9) with the bug fix is now available in the Chrome Web Store. Chrome will auto-update the extension in a few hours, or you may force a manual update to update immediately.
Original post:
There is a bug in the current published version (v. 8.31.17) of Todo.txt for Chrome that affects Dropbox integration. Login and syncing with Dropbox is broken because of this bug. Syncing with Google Drive is unaffected.
I have already submitted an update with the bug fix (v. 8.32.9).
However, due to new processes and covid19 related delays, the extensions review team and Google currently takes anywhere from 2-21 days to approve updates.
I am sorry about this issue. Hopefully, the update will get approved and rolled out quickly. I will update this post when the update is available.
