Viber does not work after upgrading XA2 Plus to 4.3

Has this been resolved for everyone? Viber (v 17.1.0.6) still won’t start for me on my Xperia 10 Plus Dual SIM running 4.3.0.15. Upon launching, the logo shows up on a white background, then after around 15 seconds, it changes to a black screen and nothing happens. I’ve granted access to storage, contacts, phone, etc. in Android support.
