TestFlight - The language specified is not listed for localization

Interesting. I tried this but I get the same error ("Sorry something went wrong. The language specified is not listed for localization") when I try to remove existing localizations under Test Information (i.e. I can't remove the localization due to the error. I wonder what I might have done differently from you?

I get the same error there too! The whole testflight localization thing in iTunesConnect seems broken.

Deleting localizations also doesn't work for me (same error). It's incredible that this is now broken for over 5 days and no one seems to care.

I got it working again after deleting some langauges under Test Information.

I get exactly the same error when trying to delete a language under Test Information. Even if I try to add a new one I keep getting the same error.

I found a fix for myself, you can this out and see if it helps

1. Go to "TestFlight" tab
2. Look for "Test Information" under the App Information on the left panel
3. Click on the laungage you are currently using which will expand and show you all the languages that are avialble for localization. (it's on the upper right of the screen, blue text, in my case, it's English(U.S))
4. Remove the languages you don't want to support for TestFlight and in case there are duplicate, just remove them all and re-add the one you really need.
5. Try to submit the TestFlight for external tester again. it should work now

In my case, there were 2 "Korean" in the list, but I just remove them all except my English (U.S.) as my primary. Note that localization for TestFlight page is independed from localization of the Store and the app itself.

Deleting languages (other then primary language) worked for me.

When I try to delete a language I get the exact same error message "The language you specific is not listed for localization." I continued deleting another language and once it removed the next language the language with the error was also gone. Once I removed all with only English left I was able to submit to external testers. This is by far not a legit fix, but it does get the build out there for external testers.

@Brian - I am facing the same issue where attempting to delete available languages would show the same error -

"Sorry, something went wrong. The language specified is not listed for localization" .

Were you able to get around this problem in any way.

Same issue here too, and I can't seem to delete any languages. When I try to delete a language I get the exact same error message "The language you specific is not listed for localization."

Same here... We're going to have to blind release this one... it's been a few days, we filed a bug a few days ago, have yet to hear anything about it...

And for the record, we have two phantom languages which just show as a resource ID:

**ITC.locale.cmn-hant**

**ITC.locale.cmn-hans**

I've tried this, but I'm getting an error when deleting two phantom languages and others too:

**ITC.locale.cmn-hant**

**ITC.locale.cmn-hans**

It says "The language specified is not listed for localization"

I finally got it to work. I just kept trying to delete TestFlight languages (I got the error each time) until one of them finally deleted. Once that language was deleted I was able to add external testers. For the record, it was Japanese that eventualy was deleted, but a couple of the other ones that I had tried (and got the error on) were deleted at the same time.

So thanks to everyone who suggested that particular course of action!

Yes, I've got one of those entries. Not sure yet if it's related at all, but it seems like not everyone has them.
