Fire TV Stick で prime videoを起動したら「エラーコード：8056」が出て起動しない

「今すぐアップデート」というのだけど、OSのバージョンは最新（らしい）

jp.amazonforum.com

どうも同じ現象の人はいそうなのだけど、サポートの人は「過去事例にない」と言ってそう。取りあえずの対応として

1. アプリのデータとキャッシュを消せ
2. Amazonアカウントのバインドをやり直せ
3. FireTV Stickを初期化して試せ

と宣っているのですが、、、1はやってみたけど現象再現。2以降は面倒なのですよね。。。

logcat取ってみた限りだとたいしたエラーは出て無さそう。ちょいちょい怪しいエラーは出てますが

一番怪しそうなのは↓で、なんとなくamaoznアカウントのbindが上手く行って無さそう？

次点が↓で再生アプリの登録に失敗してそう？

仕方ないので取りあえずAmazonアカウントのbindを解除してやり直す。。。

起動してprime videoアプリを選択したらprime videoの更新が走った。。。

そして、ちゃんと起動した。。。

umm... 面倒だ。。。
