Did you have all these apps on firmware 1.5.5 also all at the same time? Is there a noticeable change in the number of apps you can have installed at the same time?
No, I could not have all those installed at the same time while on 1.5.5. The main culprit seemed to be the ETH app. It seemed to be very large and with it installed, the number of "non BTC" apps like Stellar, NEO etc was very limited.
And yes, there is definitely a noticeable change in the number of apps you can install now!
I didn't quite understand this part. For which actions do you need to click both buttons?
When opening or exiting apps on the Ledger both buttons need to be clicked on version 1.5.5 as well.
It's more consistent now... so you no longer have "left button = X", "right button = √" options... Instead, you now select a "Approve" or "Reject" screen by scrolling left/right and then click "both buttons" to confirm your selection.
I think some pictures will explain it better:
Old system on firmwares <= 1.5.5 with "X" and "√":New system on Firmware 1.6.0:This system should prevent accidentally confirming/rejecting of something with a single button press... and makes it more consistent across the UI as all selections are now done with both buttons. This "Approve/Reject" stuff is shown when verifying addresses and transaction details before sending etc.
