I have been truncating such posts at 250 characters in the RSS feed to allow the link to be inserted so shouldn't have to do this any more.
I'm going to comment out that function and this post can serve as a test.
Micro.blog truncated the post and included a back link on the web while the iOS app included all the text without truncation.
Both options currently strip formatting and other links but the latter is next on the list of things to implement with regards to this.
I won't remove it completely just yet but, with this change in place, I should be able to leave my truncate function commented out. ?
