It is very possible that when you reconnected QBO (perhaps when you needed to due to Intuit's regulations), you signed in to the wrong company.
It is easy to check to see if this happened.
First, go to QBO and log in to the account that you connect to Mobius Connect. Check the chart of accounts and ensure that this is the correct chart of accounts that you are using.
Then go to Billing and you will find the Company ID on the top of the page. (Write that number down; we'll need it later.)
Now let's jaunt over to Mobius Connect. Look at your connect screen and you will see the Company ID number for Quick Books in the Configuration page. If it is set up correctly. The two numbers will match. If those two numbers do not match, you are linked to a different QBO account and you will need to disconnect and reconnect.
