I've owned my 5 v2 cams and one v3 for over a year. I have the Wyze SD cards in each. I finally decided to go ahead and try the cam plus subscription, and now, the only one that stays online is the v3. The three v2 cams i got the subscription for, constantly and randomly drop off of wifi, and have to be reset or just randomly decide to pop back on. I have no wifi issues, they are absolutely well within range, and i have no clue why this is now an issue besides the cam plus subscription.
