Shared Mailbox Issues1) Can’t delete phishing / spam in shared mailboxes.
2) No access to messages marked as spam.
3) Cannot easily check actual URL of link.
This means major security risks.
Makes this almost useless.
Please don’t reply telling me to contact support.
Update: Got a reply saying it is possible. Not seeing this anywhere.
I only see: Add to favorites, Watch, Copy Permalink, Tas as…
Note: I am talking about **Shared** mailboxes.

TerribleI’m shocked with how unreliable this app is. It doesn’t update contact list, sometimes it doesn’t send, it won’t link with Google.
Genuinely do not use this app.
使いにくすぎて日本語でも書きます。
絶対にやめた方がいいです。コンタクトリスト更新されない+たまにメールがエラーで送らない。酷い

Good! But More... [Ja/En]【現象】
送信元のメールアドレスをサムネイル画像設定の上連絡先に保存すると、アドレスが全て小文字にされるので、メール一覧などでサムネイル画像が反映されず、送信元の目視による判別が難しい。
【要望】下記のいずれかを対応していただけると幸いです。
1.連絡先内のアドレスの大文字を小文字に自動変換しない
2.連絡先内のアドレスと実際に来たメールの間に大文字小文字の差異があっても同一メールアドレスと判定し、サムネイル画像設定を反映する

**[Issue]**
When I save the sender’s email address to my contacts and set a thumbnail image for that contact, the email address is converted entirely to lowercase. As a result, the thumbnail image is not reflected in places such as the email list, making it difficult to visually identify the sender.
**[Request]**
I would appreciate it if you could implement either of the following:
1. Do not automatically convert uppercase letters in email addresses stored in contacts to lowercase.
2. Even if there is a difference in uppercase/lowercase letters between the email address stored in contacts and the actual sender address of the received email, treat them as the same email address and apply the configured thumbnail image.
