When I want to read the list of the blogs I follow, I can only see 1 blog, instead of the usual 30. When I click on "Show more", nothing happens.A brief affinity analysis, of current forum reports, suggests that the affected blog owners are using Draft Blogger.
One of the little realised issues with the Reading List is that access to your Reading List requires that you be identified, to Blogger, as you.
If the "One Entry" in your Reading List display is the Blogger Buzz blog, that would suggest that you are not being properly identified. Blogger Buzz is a part of every Reading List, automatically, and can't be removed. If you are only seeing Blogger Buzz, then you, the specific owner of your Reading List, are not being identified.
Reading List content is complex - and subject to various local computer and network problems. Many problems can't be resolved, by Blogger Engineering, alone.
Given the normal instructions to revert to use of Production Blogger, several blog owners have reported success.
I just switched to Production Blogger - and there's no problem now!This blog owner has just found himself experiencing the latest Draft resident bug.
To determine whether you are in Draft or Production Blogger, when you have this problem, examine your Profile URL, after you login to Blogger. An example (with a hypothetical URL):
https://www.blogger.com/profile/04234326634594848875See the difference?
Once again, I'll suggest that you use Draft Blogger to work around specific problems - and when the specific problem, affecting you, is resolved, switch back to Production Blogger. The sanity, that you save, may be your own.
