I doubt it’s too nefarious. Am sure they will fix it asap. Could be a coding issue. Could be a few assh***s reporting it. Happens to new sites with some degree of frequency. Also, even sites I have gone to for years get the occasional Google screen saying the site is dangerous.
Am sure it will all workout soon. Also, just make sure you have the most current browser downloaded. I have also found that some sites do better with different browsers. I use Firefox primarily but do use others from time to time. The site worked fine on Firefox for me.
You are extraordinarily optimistic.
Or, more likely, just gullible.
