Hopefully there is not anything "fundamentally" wrong ...  it should have been quite straightforward after the Symbol-accounts were defined. E.g. I found my XYM-account from account explorer with the importance 0.017282 % and everything seemed to be ok.

Now I cannot acces that XYM-address in the XYM-wallet, tho gave the correct mnemomic.
And the account is not found from the http://explorer.symbolblockchain.io/accounts/NCEW6I*  ... just saying "This account does not have a public key yet".

Was there some XEM limit for Opt-in accounts?   E.g. if the account  had too few XEMs, then for it is not created the XYM-account?
(Before the snapshot I moved XEMs away, coz had unidentified problems with Win10 and XYM-wallet)
