All the recent versions (1.1.82, 1.1.83, 1.1.84, etc) were added to the Amazon App Store for publication along with other Stores, but unfortunately, the Amazon App Store is still checking the uploaded versions...
We've already sent them an inquiry on this case as the last time they published the submitted version was over a month ago.
Kindly wait a bit as they might be processing the app version as we speak🙏
Do note that the developers only submit the new version of the app and then the Amazon App Store checks for any issues and publishes the app for public use.
UPDATE: Announcement to Amazon players!
