Who built that course and when?
Some courses like Hungarian have been stuck in Beta mode for a longer time.
Edit: I got the feedback on the HU sub forum that the Hungarian course is not in beta anymore.
Recently staff has rolled out a new Hungarian course update.
To get out of it the user (error) reports need to be under a specific threshold.
Requesting a course extension?
Be realistic.
It only has 291k learners.
Wasn't it created by volunteer contributors previously? Not any (old) users are shown on the course detail page! It's empty (new contract linguistic teams are not shown anywhere).
Only paid (part-time) contractors with a special access/Nda/employment contract may still have access.
Duolingo closed Incubator access for volunteer contributors last year March/April 2022 and kicked them all out before going public.
Do you really think this company which is wasting millions on cartoons, animations, new path/snake design and Ai cartoon voices to resdesign everything for Kindergarten and primary school will pay extra money to hire one of the old or new volunteers?
I'm sure for the higher demand courses like Japanese, Portuguese or Italian they have been doing this and 1+ person(s) took the role.
When new path Unit extensions are allowed, which now would actually cost them more money if someone hired is full-/part time working on new course material, is a very different question.
Well, personally I don't see this happening for minority languages which don't have yet many ACTIVE learners in the short-term, but I could be wrong.
Makes more sense (to me) to dump more money for linguistic teams into those established courses with millions of learners, where there is a real need, and to make compliant with Cefr.
Also staff has been moving to CEFR content and alignment since a longer time for the major languages (excluding Portuguese; but English from PT).
To write to them to "request" this? Hmm, they usually don't respond back anyway...
If you're Plus/Super try your luck: There is a separate Plus support email. No need to go through an "Other" bug report.
You surely will notice in the next 5-10 years, maybe sooner, if there will be any Zulu course changes.
