Is there ETA on fixing this issue in newer version of Armory?
High-S signing is fixed in 0.93.3, but if you're after official Mac binaries, you're not necessarily going to get them just yet. Downloads for Linux and Windows are in the top post of the thread "Armory 0.93.3 with BIP62 compliance"
Good news. Thank you.
I have finally managed to send mentioned transaction but during second attempt with much higher fees.
