Ever since the 2.0.8 Release earlier today, WoW won't recognize ATT in game. The add-on-list in WoW tells me that it's loaded and running, but the mini-map icon and all /att commands have no effect. As you'd expect, all in-game functionality is missing as well.

I asked in trade chat if anyone is having ATT issues as well, to which someone described a problem exactly like mine.

Same issue here. It looks like the Classic version is somehow getting mapped to Retail installs, maybe because of the major version number change to WoW. Twitch's Addons view shows AllTheThings-2_0_8_Release.zip in the "Latest Version" column, but ATT-Classic-0_3_4_Release.zip in the subheader of the "Addon" column entry.

Just noticed this happened with several of my other addons. Maybe it was a Twitch bug? Removing and reinstalling the addons appears to be working.

I removed and reinstalled ATT with no effect.

1 - The new version of ATT for the Shadowlands Prepatch hasn't been released yet
2 - If you are using Twitch to update your addons and it installs the wrong version, that is a Twitch problem.

Can confirm I now have the right version of ATT in-game, can equally confirm it's not working. Will wait for the SL version.

I attempted to revert to 2.0.7 but it's not working either. Possible it's giving me yet another classic version.

Updating to 2.0.9 fixed this issue. Thanks for addressing it.
