Monero Trezor users will experience 'four days of service disruption' after v15 HF according to matejcik
Bad news everyone. We will not be able to do a firmware release this month. The originally announced date, August 17, is back in the game. I’ve seen that you pushed back HF activation to August 13, so that is only four days of service disruption.
The v15 Monero network upgrade was only recently rescheduled due to hardware wallet and multi-sig audit delays, as previously reported4.
This is an ongoing story and the report will be updated when new information is available.
Update 22/8/17: New Trezor firmware was released5.
