Сферический ВК в вакууме
IT corporations remind me of some of my relatives. They are also incapable of remembering those of my preferences that they don't like, instead asking me same things over and over again and acting very surprised every time, despite knowing me for several decades.
To add insult to the injury, the easiest way out of these unwanted modals — the back button — does nothing for this particular one. For Google, this whole RCS crap is apparently a Big Deal™.
