So, if you were paying attention:, you would know:
- the last stable version was 2.3.3, released last May;
- Back in June ZWO issued a version 2.4 quickly followed by a public apology for the bugs created;
- despite four beta versions ZWO added a bucnh of new features but also broke a lot of functions that previously worked perfectly well;
- ZWO has not fixed the bugs, ie what they broke.
The intriguing part is that it could possibly be a deliberate ploy to lock users in to an all-ZWO ecosystem, as it appears those using small rigs on AM3/AM5 think it works, yet for anyone else its effectively unusable.
The instructions on how to revert to 2.3.3 are available in section 21 of ASIAir: The Missing Manual.
