For the past couple of weeks, I have to click on the Discussions button at the top of the MFO home page to get the thread I have just read to refresh. If I use my Back button (arrow) the thread does not update and it appears that I have not read it. I rely on the refresh to navigate through the board to find previous threads I may wish to read where I left off on my previous visit. The problem seems to affect my iPad, but not so much my MacBook Pro or iMac. I don’t read on the iPhone. Thanks for suggestions.
