If you are interested in pairing devices, here is my pairing code:
AmOIR5s+WxMyYUhUbEUwvr4lSP68ftSd9My8vJ1Esz2/@byteball.org/bb#gnSZxT7d0S2R
Remember, this is for one-time use, the code won't work for the second person.
I actually tried pairing two of my devices by adding the pairing code from one to the other but this doesn't seem to be enough (I chatted from one device to another but never received messages), maybe I need to perform the operation on both devices? or maybe both must be online?
It is enough. If the devices are listed in each other's list of paired devices, they should be able to chat.
Some observations:
- 0 is considered as a valid amount, I mean when I type 0, Not valid does not appear (whereas it appears for -1 for instance), however 0 does not trigger the SEND button (which is normal), so maybe 0 should be considered not valid.
Agreed, a minor glitch.
- When writing a very long number the digits overlap on bytes.
That's a really long number, are you a whale?

- I tried sending very large numbers and it resulted in sending 1 or 2 bytes.
Thank you for spotting, will investigate.
- Why is it compulsory to backup the wallet keys before receiving a payment?
Actually, it shouldn't be compulsory, I copied it from Copay and didn't change. Will fix.
