I had some weird issues this morning (7/3/19) where the Community wouldn’t let me in on my phone 
I closed all of the tabs I had open and then closed the Chrome App I use as a web browser.
Then I reopened the app, went to USCCA.com and logged in. After that I went to the Community at USCCA.com/community and things were back to normal.
If you’re having issues and trying this doesn’t solve it, please shoot me an email at support@uscca.com
I check that email daily - if not more often 
Had an issue late last night on my phone… said the site was in read-only mode and wouldn’t let me like or respond to posts
That’s the same issue I was having. There may have been a programming update or a backup running which booted us out.
Same on mine Dawn; said I needed to make sure I make a comment by tapping on a Reply button (strange and true) nothing I felt I needed to comment on everything possible was already commented on. I thought I logged out yesterday but discovered I didn’t. But I tried again this morning and all was fine again.
Just last night but Everything is fine today.
Had the same early this am. By break time, all was fine.
It started sometime between 2 and 3 am this morning. I thought it was just me because of the storm that was rolling through at that time but from what everyone is saying it almost sounds like a network issue someplace. Possibly not connecting to the authentication server correctly? Other option I see from that point of view is router interface issue (not necessarily in-house)
I was last night but all fine today Zee
