So If I have this right it may be possible to recover these amounts.
That depends on what you did.
The link won't help you recover anything.
The link is just a way to ask for a payment.
If you have a Jaxx wallet, and the Jaxx wallet has bitcoins, then you can send them without the link. Just enter into the Jaxx wallet the amount of bitcoins that you want to send, and the address that you want to send them to.
If you don't have a Jaxx wallet, or your Jaxx wallet doesn't have bitcoins, then the link isn't going to magically put bitcoins into the Jaxx wallet for it to send to you.
You haven't explained yet how you "lost" the bitcoins, so it isn't possible to explain to you if you can recover them or how.
Well, I suppose I knew it couldn't be that easy!
Okay, here's the story as simply as I can describe it.
1) Installed Jaxx wallet on Android.
2) Wrote down seed phrase
3) Sent various amounts to that wallet from Coinbase and ABRA. All showed fine.
4) Installed pc version of Jaxx and tried to pair wallets. Didn't work for some reason so I just let it be since the Android worked fine.
4) Was given a small amount of BTC by joining a crypto newsletter. Tried sending that to the pc wallet and it worked.
5) Then tried again to pair the wallets.
6) Result: ALL BTC disappeared from the Android. Only the small amount was left on the pc version.
I'm 100% positive that the seed phrase I wrote down is the same seed phrase I received when opening the Android wallet.
Since I only tried to pair the pc version I did not get a seed phrase with the desktop version.
Whatever everyone tells me is that I must have received a second seed phrase. Secondly, I did the pairing wrong and the PC overrode the Android. And finally, without that other seed phrase the Android BTC is gone.
There you have it.
