So, the issue is related to transient languages. It’s discussed here:
You had sent me your keyboard which is associated with the oma language, but when I install the keyboard it indeed gets associated with “English (United States)”.
When I go into “Configuration”
I can click on Add/Remove Language
And try to add Omaha-Ponca, I get this message
When I uninstalled one of my other keyboards (BJCReeUNI (east)) and then went back to Ponca Sky and clicked on Add/remove language I was then able to select Omaha-Ponca AND remove English. Now, I have this:
And I’m able to select the keyboard that is associated with oma.
I’m sorry it’s taken so long to realize that’s what the issue was. Thanks to @mengheng for pinging me again.
