I'm using the latest version of Alfred (4.0.5) on Mac Catalina (latest public build 10.15). Whenever type in 'find <file or folder' Alfred shows "Waiting for Results" for many seconds (at least 10) before finally finding my results. Spotlight will return with the results immediately and previously Alfred 3 on Mojave was also instantaneous. The delay is quite frustrating and makes this type of searching pretty much unusable.
