Note: even going into MD category to search is also fine.
Also yes, this is something you should contact the app devs instead of MD. I really wonder why people going to MD for these things when the apps are not developed by MD, thus making them not MD's responsibility
@christianbobsin Tachi isn't using the new API, we haven't changed anything else, and I haven't seen anyone else with search issues. Are you still logged into the extension?
