I have been using Pocket + p2k for long articles that I prefer to read on Kindle. There are several issues with the setup, but this works well enough for most articles that I have sticked to it over the years. Looks like I have to find an alternative now.

I've been using wallabag for a while, switched to Pocket for this exact reason. Maybe switching back is the answer to this? Looked around a bit, someone seems to have thought about this already.
