Thank you for your reply @timl !
I had not seen that post. We tried with IE, Chrome and Edge: same problem.
But, I did see a reply from Marianne Christensen in the post thread stating:
Yes, the solution was to have English as Windows Language.
Now that's interesting. Indeed, my users have system set up in French (Canada). Mine is in English. If this is indeed the problem, it is a bug. In Quebec, there are legal considerations regarding the language used at work and I can't just switch my user's Windows Language to English. Perhaps I should submit an idea to get this bug solved?
