Yes, both linking and registration should work again!
However: if you currently have a working linked Whisperfish, it does not automatically get updated to be PNI-compatible, and you will not see any new conversations on that device.
So:
- Pre-beta.25 existing registration + Whisperfish is primary: OK
- Pre-beta.25 existing registration + Whisperfish is secondary/linked: problem with new conversations
(Implement PNI (#459) · Issues · Whisperfish / Whisperfish - Signal on Sailfish OS · GitLab) - Post-beta.25 new registration + Whisperfish is primary: OK
- Post-beta.25 new registration + Whisperfish is secondary/linked: OK
A workaround for (2) is to unlink the device, remove the data directory (perform a reset) and link Whisperfish cleanly: that brings you into situation (4), but erases all your conversations from your device.
