Describe the bug Trying to remove from the app an account no more existing became impossible because the app requires a previous deactivation of the notification. So, if I decide to delete an account on my server, I can't do it because I have to remove it before on the app. It's pretty strange to me.

Details (please complete the following information):

• Siskin Version: [e.g. 6.4]
• iOS version [e.g. 14.6]
• iPhone model [e.g. iPhone 12]
