Unable to enter two voice channels on my guild’s Discord

When I’m using Discord on my phone or PV, I am unable to join one of two voice channels on my guild’s server. Other servers work judt fine. I’s weird becythe channel appears in compact mode, and I can’t click on it or interact with it in anyway. My servers admins insist that my permissions are fine. Yesterday, thid behavior spread to the other voice channel in out server. The AFK channel is just fine. What’s really weird is that if I completely uninstall Discord from my iPhone and reinstall, the problem goes away. It comes back if I close the Discord app. Nothing I’ve tried on my PC helps. I’m a legally blind tank in Classic WoW, and the ability to use voice is vital to my sucrose. I’m subscribed to a number of servers, but only my guild’s server is affected by this. I’m also the only one in my guild with this issue. Any insight as to what I can do about this would be great.
