Delay before seeing usernames


On my mother’s phone, I was able to find her contact on my phone a few minutes after she created her username. With my father’s phone configured a few minutes later, I still can’t see it on my phone 24 hours after he created it. After 24 hours, it appeared on my computer but I still can’t see it on my phone, for the same account.

I just rebooted the phone and now I’m able to search for my father’s username.

I can’t understand what could create such different behaviours. Probably because the phone are not always connected to the network or because Jami has been put to deep sleep by Android. But for sure, acceptation of Jami by non-technophile people is based on first impressions, and not being able to explain such behaviours does not help spread Jami.
