Since upgrading to 7.48, when i bring in a new epub book and wish to convert to mobi and send to kindle I find the following occurs:
1. Job #1 occurs that lasts 4 to 5 seconds. No file is sent
2. Resending results in Job #2 which appears (shows a correct mg number) to send the file
3. Sent files arrive less than 50% of the time - but sometimes they do arrive.
4. I send to firstname.lastname@example.org
or to a friends kindle email using their assigned kindle email where I have been registered on their amazon kindle account as a valid sender.
The system has worked reliably in the past but the short "job" and unreliable receipt of the files has started with the 7.48 upgrade.
I would appreciate help. my email address is email@example.com
BTW, Kudos to kovid. This is a great service. And, i am an enthusiastic contributor and promoter.
