I have never heard that they keep on saying that it has been decided and not decided and then decided.
When an application has really been decided, it takes between 4-10 working days to arrive. So, apart from this transit period, all applications are by default "under consideration" or "awaiting decision". It has been the case for decades or possibly centuries.
Another tracking system could look like this.
