DeathAdder V2 Pro Scroll button broken by firmware update

After firmware update via DeathAdder V2 Pro_Mouse_FirmwareUpdater_v2.03.00_r1.exe, for my mouse a RZ01-03350100, the scroll wheel button no longer works.

I downloaded the Synapse software but see no way to test or fix this issue.

The left and right buttons and scroll up and down work, but not the scroll button, I can't tell if mouse button 4 and 5 are working. I tried a few on-line mouse button test pages neither the scroll button or mouse buttons 4 and 5 show as working.

Any better way to test?

Is there a way to down grade the firmware to fix the issue?

The mouse is only a few months old from Amazon, July 2022 from the Razer Store.

Did you already try to reboot your PC or test the mouse on a different PC? Once updated, the firmware cannot be reverted to its previous version. It's best that you PM me the serial number so I can validate its model and coordinate with the relevant team to know our options. Thanks!
