I've also tried with existing dataset in the settings flash:
- I flash ot-cli-ftd from 0247d02b9dbfb437a1b8e81040323937814e0aab
- I attach to the existing network
- I flash the new build from 5a92680
- Now
dataset activereports the correct network details, including the correct mesh local prefix ipaddrstill shows the (wrong) `fdde:ad00:beef::/64" prefix- The node doesn't actually manage to connect to the existing network, it becomes a "leader" with no neighbors (and if I repeat the process with additional dongles, they, too become isolated leaders).

@TPolzer , can you provide the output of dataset active for your existing Thread network? In particular, what is the Active Timestamp value? In order for the Attach to Existing Network steps to succeed, the Active Timestamp of the existing network must be non-zero.

Flashing two dongles with the new openthread version and a fresh dataset (dataset init new on one of them) works btw.

I'm wondering whether it has something to do with timesync being enabled in the existing network. Though
- my understanding is attaching as a child should still work
- I tried compiling the new openthread with
-DOT_TIME_SYNC=true, the observed behavior (see #223 (comment)) is identical, time sync works:

This seems related to the issue reported in this openthread-users email.
I have submitted a proposed fix in openthread/openthread#7323. Let me know if this addresses your issue.
