I have a two facebook accounts. One I only access every few weeks or months. However I can only ever see the last day or last few days of posts. Therefore I must be missing many posts which presumably people will expect me to have seen. There is no option for older posts at the bottom of the page.
Whereas on my other account I can scroll down using the older posts option. I have separate email addresses for the 2 accounts and access both via a PC and never via a table or phone if that makes a difference. Any ideas as I have no technical ability especially regarding facebook.
