This is exactly the kind of response that says your management is being filled with people who don't understand how business works (you are an accounting system company!!), and your company is starting to decline and going the way of Blackberry and Nokia.
Unfortunately all those who had counted on and trusted your company (like us) will suffer. Your most loyal customers will suffer the most. We have trusted QBO as the heart and bedrock of our business since starting.

But luckily I see someone in charge has more sense and the Mobile number is back.

Next please add back the Business Registration Number under Account and Settings.
SST is there, but the BRN which is much more important info is not. Every single company worldwide has its BRN.

Advice - don't try to be smart, focus on doing simple basic things properly.
(eg kudos for doing the dark mode)
