The sent email is not in the "sent" folder

Description

I just sent an email that, although it was successfully sent, is not in the -sent- folder of my account, nor is it in any other folder. I’ve sent several other email, and this is the 2nd time it happen.

To Reproduce…

I don’t know how to reproduce because usually the email that I send are correctly moved in the “sent” folder

Expected Behavior

The sent email should be showed in the “sent” folder, not disappear

Well… nobody had this issue???
I really like Mailspring, but I keep having this huge problem (just sent 2 emails, none in the “sent” folder!)
Am I the only one that experienced this bug?
I think that I’ll have to move to another email client if there’s no support at all for some crucial not working features like this one :expressionless:
