when can we expect an iOS wallet release? is there even a plan to develop one?
There was a plan for an official wallet but now dev's time is packed with other tasks. Try SatoWallet or PolisPay for ios. Many users praised SatoWallet but I didn't use it. Join the community and ask for an official ios wallet. If a lot of users push it hopefully the devs will make it.
I'm using SatoWallet, and can confirm that is working well, but I will feel safer to keep them on an official iOS wallet
Of course nothing beats an official wallet. You can always use a tiny device to run the desktop wallet. It's available for Windows, Mac, Linux, Debian, Raspberry pi and other operating systems.
Installed & synced 2.0.1 and Now few hundred coins are missing. What to do Now?
It's a known issue. There is a fix but it's easier for novice users to use the previous wallet until it is fixed. There is a new update which is being tested for the past 4 days but not yet released.
