But I think that it's irrelevant, since as you also said, the problem is most probably the (lack of) memory.
The one I mentioned it's a separate issue... From what I've understood, the Fido U2F app it's not showing up on the Ledger Live.That is incorrect. I've made a screenshot, search does return Fido U2F.
The thing is that after the firmware update there are no apps at all and it asks if you want to reinstall them. If there's no space for them, some may not be reinstalled and I don't know if it returns a proper error message or not.
I wouldn't be surprised to see them end its support in a year or two!
I would be even more disappointed if this would happen. They still sell Nano S, you know...
And even if the firmware won't be updated (except very big security problems), the apps still evolve. It doesn't matter if it'll be only Bitcoin app that fits, I'd expect that after a while, but no actually end of support, not yet. Maybe 2-3 years after they stop selling it...
