We're really struggling with the fact it seems to be taking up to 3 days for all updates to our site to come through on mobile (works immediately on desktop) eg. deleted projects still showing. This site is going to be updated very regularly so poses quite a big problem for us in the future. Any ideas on how to solve this problem?
Hello please try the following things:
On your iPhone safari or other browser, activate "private browsing mode" and take another look.
Turn off wifi on your phone and take a look.
Could be possible you have custom phone layouts activated and you don't edit your custom phone layout, you just edit your desktop layout and wonder why the phone version is still the same.
Talk to your webhost and ask them why this might happen.
Disable any non-laytheme plugins.
