Because yesterday, when i saw that btc receiving address and then click okay and verified. i then click on receive tab again and did same thing to generate btc receiving address and it showed the same exact one again. Did it again and it kept showing the same btc receiving address. But that is normal?
I already explained that receiving address 1 has to be funded before Ledger Live will generate and display receiving address 2. It's logical that if you generate a new address, close the software, generate an address again, LL will display the same address in both cases. The first address never received any coins, you will be seeing it until some BTC is transferred to it. It's normal.
I can't concentrate on your unnecessary walls of text. I will only answer what I remember reading it the first time.
When you click on any transaction you received in LL, you will see the transaction history. No idea why you have problems understanding the information shown there. But there is also a link taking you to a blockchain explorer where you can see the addresses involved in the transaction. Click on it. Alternatively, connect, and open your wallet in Electrum and check the addresses tab. It will show you all funded addresses and the balances.
To check your portfolio in Ledger Live, click on the "Accounts" tab. All your Bitcoin and altcoin accounts will be displayed there and the balances will be clearly shown for all of them.
