更新改版後跟原來介面顏色不同

更新改版後跟原來介面顏色不同,看了很吃力之外,月曆會有上下月的顏色透明度太淡,使用上也變複雜不好用

ほんとに使いづらい

10年以上前から使って居ましたが、ここ1-2年のAI導入からバージョンアップのたびに、ほんとに使いづらくなってきた。
長年使っていたので変えるに変えられなく困っている。
よく、こんな使いづらい改悪できると思う。作者はおそらく使ってないのであろう。操作性が煩雑になり全くなってなくてイライラする
使いもしないAI機能なんて要らない

Deception after system changed to AI

I used a lot this calendar, since they change it to AI system is really difficult to follow, too much information and dashboard not very friendly. I liked how it was before.

初めは戸惑うが、慣れて来ると期待できそう

長い間、以前のバージョンを使用して直感的に使用してきていたので新バージョンにアップデートされ戸惑いかまありした。ただ日々使うアプリなので何日か使う内に次第に使用感は良くなってきています。慣れて来ると新たな機能を使用するゆとりもでき使い勝手は向上すると感じます

時間設定不見了
