@srschizo I don't see any flaws in AndStatus v.22.5 that would require to downgrade or fix it immediately.
Regarding empty timeline, if "Refresh" and switching between timelines don't help, you can always restart the application by deleting it from Android list of "Recent/ active applications". Actually your "downgrade" fixed a problem exactly because any installation restarts an application.
Regarding a root cause of a Timeline not being loaded / updated, I'm working on one of probable problems that was there for years, but only could become more visible recently, because more actions in AndStatus became asynchronous https://github.com/andstatus/andstatus/issues/281
