Can't add category to Expense

Can't add category to Expense

Zoho app has worked great until yesterday (March 13, 2024).  I can put the information on an expense (vendor, amount, receipt) --- however, when I go to one of the categories I use regularly it is in the "Recently Used."  When I click on it, nothing happens.  It will not load. 

Yes, there's an option to add a category, but then I'd have to get company approval, account code, etc.

No idea while it's worked perfect for the last year and now this is stuck.  Is there a way to fix it??
