Philip, please reach out to our Tech Support as this behavior isn't normal.

@Philip Zima Yes, we see this as well. We notice that a dark theme gets reset. Other than that, settings are sticky. Do you see any other setting that don't stick beyond the dark theme? I would love to know and educate our staff to watch out for settings that don't stick.

Did you report the issue to RingCentral like @Anirban or @Mary-Community_Moderator suggested? If so, did you get any response?

I just talked to Ring Central Support (2021-05-12). They indicated that this is a glitch. Voting for them to fix it is necessary to push it to the top and help them decide if they are really going to fix it or not.

This is inconvenient! It really needs to be fixed. I generally just leave mine open, so I don't have to fix it each day. But that isn't really a good a idea.

I am finding that we are having the same issues as well when it comes to "theme settings" and "sound/microphone" settings too. Each time after logging out/logging in I have to set my settings again.

It happens to me also. Every time you sign out or windows sign's out for me for updates overnight, it goes back to default mode. I have to set dark mode every time.

For those who have the same issue, kindly coordinate with Technical Support Team. Thank you!
