Not an ideal solution, but as a workaround, from a security perspective, you might be better switching IR to always on. Apparently that works and yes it’s a compromise, because if you don’t remember to switch it off, or set it back to auto, your daytime shots will be in black and white, but at least you won’t end up with nothing at night, for what might be a significant event. Do your own test, when dark, having set it to on, and adjust intensity as required, and see if it works for you as it has for others.
Not defending Blink, in my opinion it should have been rolled back immediately, as soon as the first reports came in, but at least you don’t have to send it back, if you’re prepared to wait. I’m sure there’ll be a fix, in the not too distant future and in the meantime, the worst you should have to face is a black and white daytime video.
I don’t know why they don’t roll them back when such things happen, it seems obvious to me. Similar things have happened a number of times since I’ve owned Blink, which is only around nine months, and each time I’ve been perplexed about why they don’t roll back. I can only think that other bundled enhancements outweigh the drawback, in their opinion, but what those might be I couldn’t say. If it is that, I think they should work with one thing at a time, but then they were/are probably under severe pressure to get the XT2 operating more like it should, with the multiple reported issues by many.
We’d have a better idea, if they had release notes, but I’ve never found those, if indeed they exist in the public domain. Shame really, the last time a similar event occurred, I thought, surely this will be a lesson learned, and it won’t happen again, but here we are.
All I’d suggest to anyone, if you didn’t already, is to log a support ticket, just so that they’ll get a better feel for the significance of the issue.
