When I click "Choose file" nothing happens.
Please tell me - can you reproduce this in any browser? If so, which one did you try? This feature may not be fully available through some of our extensions. Such add-ins as our Outlook plugin are based on the Chromium engine which unfortunately can't support uploading of files.
I was able to upload the templates on the todoist website using Chrome, but I’m having trouble uploading other files on Chrome. I tied Firefox and Explorer and it seems to work on those, so I guess I’ll stick with one of those. I’m a little disappointed it doesn’t work through the Outlook plugin.
