old gmail emails

I can not see my old gmail messages (from mid Feb 2019) in the inbox.  How do I view them?

I have also configured yahoo email  and i can see my yahoo old messages in the inbox.

Thanks,
Anil

Not sure about yahoo, but check you imap setting on gmail.com.   There is a place to limit the number of message shown in imap.  You can increase it, or set it to all.

Thanks Barbara. Your solution worked.
