@Simon3456 I created a transaction using my light wallet.
I see that it appeared in my mempool on the server.
Someone else mined a block, and they did not include the tx.
The tx is still in my mempool.
I manually shared the tx with Sy's server. His explorer shows that my balance changed.
I check Gonzalo's server. His explorer shows that my balance has not yet changed.
It seems that the manual tools for sharing txs are working correctly, but they are not happening automatically.
