Yes, right now we essentially have two parallel spotting systems. Old code that hasn’t been updated is using API2. VK Port-a-log, SOTA Goat, SOTA Activator, SOTA Spotter to name a few.
We will get this sorted, but for now I recommend only using SOTAWatch, SOTLAS, APRS2SOTA, or SMS to send / receive spots.
This is a temporary situation that will get resolved.
