I'm really struggling to get my head around some of this. Have I got this right?
The sender cannot identify the receiver's address???? Can't be true surely????
A Payment ID is needed for exchanges because they use a 'collective' receiving address and the Payment ID is necessary for account crediting??? This is insane!!!! Can't be true surely? If this is true this feature should be shouted from the rooftops as other wallets use completely unecessary Payment ID's and Data fields and I suspect most people will be used to that. I mean this is a truly terrible idea. If I send to an address I expect it to reach an address and that address if on my account to be my address. How much Monero is being lost like this?
I've got View and Spend keys and of course my seed phrase and address.
MoneroExplorer.com reveals the following. I can't work out what any of it means. I've spent days on this and can only think the place for help with MyMonero is somehow evading me. I have noticed a number of people with very similar issues to this one never seem to get answered across multiple locations.

I notice the above has this at the bottom: "Note: without private spendkey, it is impossible to know whether this is your real spending. So do not take this number seriously. It is probably totally wrong anyway."
I have my spend key... what do I do with and where? Is it relevant? I don't know.
