My client added 2 blog posts (1 Dutch & 1 English) and has asked me to link these two blog posts: hidden link hidden link
When clicking on Connect with translations on the English blog post, the Dutch blog post does not appear in the list of blog posts with which the blog post can be connected.
The Dutch blog post does not even offer the Connect with translations option.
It being a Friday night I might only respond to your response tomorrow or Monday.
The Dutch page had an English translation started, so it was showing as In Progress which was why it couldn't be connected. I went to WPML -> Translation Dashboard -> Jobs and cancelled the in progress job. After that I was able to click Connect with Translations, and I connected it with English. I confirned it is working and I can now see the language switcher showing both languages on the fronted.
Please let me know if you need any further assistance and I will be happy to help.
