Operating compatablity delay

Hi, I’m really concerned about the delay with operating system updates. I’ve had to tell my customers that they need to rely on windows defender or not run certain software of their devices. Mac OS Big Sur 11.1 has been out for 6 weeks and Android 11 OS has been out for almost 20 weeks. I even received an email from support saying that Comodo is now compatible with Android 11 but it is not. This is hurting my business and would like know if this issue will be resolved in the future. I cant leave or sell devices that are not protected.
