Glad to hear from you again. I'll be happy to share more info on how locations can get lost and how to create new ones. Location tracking is used to categorize data from different locations, offices, regions, outlets, or departments of the same company. This feature lets you see all the payments for one location and deposit them as a group.
The only way a location a transaction can disappear from an account is if it's deleted from the system I encourage you to check the audit log to see what may have happened to the transactions. The quickest way to view any transactions you've processed in QuickBooks is using the Audit log. You can see the changes made to your books and who made them using the audit log. It also tracks user login/logout activity, changes to settings, customers, suppliers, and employees. Since you're looking for what happened with the transactions, review the following steps for further instructions.
Here are the steps on how to access the audit log:
Go to Settings ⚙ and select Audit Log.
Use the fields on the Filter panel to choose the appropriate User, Date, or Events filter to narrow the results.
The other reason why you could lose your location is if you've downgraded from the Plus plan to other subscription plans. The Location feature only works using QuickBooks Online Plus. To learn more about this feature, check out this helpful article: Set up and use location tracking.
