I have recently updated to 7.1 and can only see emails in my inbox back to 6 July

Hello Richard,

What email account has this kind of issue?

In Menu > Tools > Accounts > Diagnostics you can try to run the diagnostic feature that will check your account settings.
If it is an IMAP account, please try removing the account and configuring it once again.

I have tried that but still cannot access my old emails
