The Russians conduct massive raids on trade facilities in the temporarily occupied territories in order to uncover the facts of hryvnia settlements with the population, but the circulation of the hryvnia does not stop.
They demand to set price tags only in rubles but the population switched to cashless payment in result. And sellers still indicate the price in hryvnias.
At the same time, the enemy seizes the terminals and threatens with fines. However, except for large retail chains (captured), the local population ignores the ruble.
Note that this is another reality that disproves the Russian myth about the “referendum” and local support, because the hryvnia is the same national symbol as the flag or coat of arms.
