Yesterday I added a lot of content including a regularly updating overview page with links out to the new article pages.
I did all this work on desktop and the pages were being updated fine, including front page and updates to the overview page.
When I looked on my mobile device I noticed probably the last two or three hours' worth of updates were not being displayed. The front page didn't have the newest articles and the overview page was out of date. The newest article pages were there, though, as I tested them including via my social media links.
This continued for a short while even after clearing the cache for the front page and overview page.
After about an hour I did a reload on mobile and everything was up to date.
I don't usually check on mobile after I've updated content but yesterday was quite a busy day for new posts. Is this a new issue with the cache being cleared quite slowly or just an anomaly?
