This is concerning. Right now the two official servers are not functional. The free2z lightwalletd is running fine but I assume if a lot of people move to it that it will suffer from the same problems

zecwallet.co is returning 502. lightwalletd.com is behind (almost caught up again tho). zuul.free2z is working but I can tell that the traffic is not extremely high because it’s not using all that much bandwidth.
All wallets should allow users to change servers. Empirically blaze sync doesn’t work for me with the big blocks and old wallet, warp sync does. Are there any theoretical reasons why blaze sync would be preferred?
After 6 days I decided to reach out to Ledger Support. Very kind and helpfull. However the solution according to them would be to buy a different brand of hardware wallet
On another note, the CEO of Ledger shared on twitter spaces, Zooko was present, that if the Zcash Community wants to have shielded ZEC on ledger it is possible that a third party can build this and integrate it with their platform.
We completed the app long time ago.
Unfortunately, it was never integrated in a web or desktop wallet. Without that, it was not possible to submit to Ledger because it was not possible to use the app. We tried to coordinate and get support to get this used in zecwallet although it was not under our engagement.
More recently, we decided to move forward with integrating ourselves into Zecwallet so there is finally some application that uses the Ledger app we developed. As part of that effort, we have upgraded the app, added support for new devices, improve the code base and we are finalizing the integration. Our team is really looking forward to seeing this being use on a daily basis…
A shame it couldn’t get that integration (seems Trezor will win that race), but glad to hear Zecwallet benefits. Maybe it can also find its way into YWallet as well.
Nano S was originally supported (within the timeline of our development).
Since the time we completed the project (long ago), Ledger kept increase SDK sizes, etc.
Due to the device limitations, Ledger decided to discontinue Ledger Nano S in June:
The recommended and available devices at the moment are Nano X and S+
There’s no special unit requirement for S+ so you can sideload the app without any issue (except a few annoying prompts about app not genuine etc etc).
As a matter of fact, you’ll be seeing such setup at ZCon3 soon
