Twin app Bug whatsapp
There is particular bug which has arrived after android 10 update. Twin app's whatsapp is unable to open any excel, pdf, word etc files. The same file opens perfectly on Main Whatsapp. Also the same file shows blank on twin app but opens fine on main Whatsapp.
There is another problem, the Twin whatsapp says to save the document first on device and doesnot open.
I am attaching screenshot so it might be more clearer.
