Hi,

Minimum steps to get a working CRM in Odoo Online

Create a fresh Odoo Online database (free trial is fine).

Install CRM, and make sure Sales and Contacts modules are also installed.

Complete the initial setup wizard when you first login:

Company info

Users & roles

Default currency & language

Assign yourself the CRM Manager role (or Administrator) so permissions aren’t blocking you.

Open CRM again; you should now be able to create Leads or Opportunities.

Hope it helps.

I just checked your database and was not able to replicate the problem.

I also ran the CLICK EVERYWHERE test and did not run into any problems.
