on Windows 10 - Mailspring 1.6.0 (I already had this same problem several times with version 1.5.7)
1/ I am writing a new message or I am writing a reply
2/ I attach files. (small files size: less than 1 MB)
I select several files at the same time, only 2 or 3 files.
the problem occurred with files .pdf or .png
3/ then in the “new message” window or when I answer, I can see the attached files
4/ when I click on the “Send” button, the message is sent without including the attached files
I can also see in the “Sent” folder, that this message has no attached file
The trouble is that this problem is not repeated (the other days), and I do not know why there is this problem.
when the problem occurs, I’m blocked. I tried to solve it:
1/ I restart Mailspring, but when I send again message with attached files. I have the same situation, the message is sent without the attached files.
I don’t think it’s related to a server problem, on the email side because that same day and same time, when I use another mail client with the same sending settings , I don’t have this problem and the attached files (the same ones) are included in the sent message.
This problem is not regular or not every time. This problem is with all my email accounts but irregularly.
