In our last update we mentioned that Amazon's latest software update (version 5.15.1) for Kindle devices has affected how covers are displayed.
In the past, Amazon generated covers for documents without cover images (such as the articles processed by Push to Kindle).
In their latest update they now use the first image found as the cover image. These are rarely suitable for covers, which makes identifying articles from the home screen very difficult.
To address this change, we are now generating cover images in Push to Kindle using the article title and site name:
Speed improvements
We've received reports from some users that sending speed has been slow lately. We think we've identified the cause and have put a fix in. If you still experience slow sending, please do let us know. (It is easier for us to identify the problem if you can provide a URL to an article that is slow to send too.)
Finally, thank you for all your continued support. We wouldn't be able to continue working on Push to Kindle without it.
