I have a Galaxy S5. I was prompted to update the software on 8/8/17, but didn't download it until about 2am on 8/9/17. An hour later I tried to sync my Fitbit Blaze, but was no longer able to and haven't been able to sync since then without restarting both my phone and tracker. With the complaints in this discussion board alone in addition to my own experience, it seems pretty clear the problem lies in the security patch pushed by Verizon on 8/8/17. I am asking that Verizon acknowledge there is a problem with the software update and please fix it as soon as possible.
