Push notification on multiple account

Good morning, Yesterday I wrote a comment about the Thunderbird app and support asked me to submit a report. I then received an email telling me to open a ticket—I honestly don't know how—or to send an email. Here's my problem: 1) The most serious issue is that push notifications aren't working as described. Specifically, I disabled battery restrictions, selected the primary account, went to folder management, and enabled push notifications in the inbox. I tested it by sending an email, and everything worked perfectly. Then I went to the second account I registered, then folder management, and that's where the problem arises. Regardless of the account I use, it always lets me manage folders only from the first account, and that's a major problem. Despite this, even after 15 minutes or with the app open, I still don't receive emails for the accounts, not even after an hour. I have to force the emails to be received, and then Thunderbird shows them to me. 2) In the combined view, it's not possible to move emails into the folders of the mailbox to which they belong. I'm forced to go into the specific mailbox each time and operate. I've tried various clients, and none of the combined view forces you to go into the specific mailbox. 3) Absurd attachment management. If an email has an attachment, I have to click three times to change the view each time. The first click switches from the combined view to the email, the second click switches from the email to the attachments. The third click finally opens the attachments. Other clients just click on the preview. I look forward to your feedback. Thank you. Julian
