So about a month ago I found out there was new firmware for the Anker SoundCore 2. At the time I didn't have any issues with my speaker, but because I like updates regretfully upgraded. The firmware I updated to is A3105_SoundCore_2_V047-20180712.fw.zip, and appears to be the latest one. After doing this update I started getting horrible lag in my speaker. When I first start listening/watching something there's no noticeable delay. After a minute or so the delay kicks in, and remains in effect until I restart the speaker; which will again start to lag after several minutes. I also noticed that when charging the speaker, it no longer turns the red led white when it's finished; it just turns it off. Is this the correct functionality with the new firmware? I tried reflashing the current firmware several times, thinking maybe there was a bad flash, but it hasn't helped. Are there downloads available for the older SoundCore 2 firmware?
