@GeetaSarvadnya see also #23206

[AlexeyBarabash]

This happens because the PR brave/brave-core#12300
is in Nightly but not yet migrated to Beta/Stable.

Nightly uses time-limited sync code words, 25 words in phrase.
Beta and Stable - use old sync code words, 24 words.
Nightly can accept words from Beta/Stable, till August 2022. But Beta/Stable cannot accept words from Nightly.

A workaround:
If it is required to use codephrase from Nightly on Stable/Beta, it is possible to remove manually the last 25th word from the codephrase before entering the sync chain.

Marking as wont fix. Will close when time-limited codewords will reach Stable, July 12, 2022

@GeetaSarvadnya was re-opening the above an accident? Looks like it's labelled as closed/wontfix as per #23428 (comment). The above is expected until one-time sync codes get on all the channels. Currently it's only on 1.42.x & 1.41.x.

@kjozwiak I had closed it without seeing the last comment from @AlexeyBarabash Marking as wont fix. Will close when time-limited codewords will reach Stable, [July 12, 2022](https://github.com/brave/brave-browser/wiki/Brave-Release-Schedule#release-channel-dates) after seeing the comments I have opened the issue again.

@AlexeyBarabash assuming the above isn't valid anymore? It's labelled as closed/wontfix. Can we close this off? If it's still an issue that needs to be addressed, we should remove the closed/wontfix label and re-triage. But I believe this is working as users have been syncing between different channels for some time now.

@kjozwiak Sorry, I missed this discussion

Yes, it's good to close because the issue is not reproducible anymore
