Kvarken installing Signal messenger

The Kvarken release notes state ‘Signal messaging app gets the contacts from Sailfish now’ but I can’t get Signal sucessfully installed on my Xperia X from the 5.13.8 apk - it either will not send or not receive the verification code - any advice much appreciated

That only applies to Android App Support (Xperia XA2, 10 and 10 II), it’s listed in this section
