Stinger missile was used in Idlib few year prior, by Turkish forces or supplied to small amount to proxies. Based on footage, Stinger had poor performance engaging low flying fighter aircraft. Now this could be operator error. I don't know the variant of Stinger is used but Stinger did not get an updated variant against new countermeasure systems. Russian aircraft avoided Stinger with maneuvers and flares in the footage. Previously, also against limited 2-3nd generation MANPADS use by Syrian rebels. Meanwhile, proving to be effective against helicopters and ground attack aircraft like Su-25.
Tactics can be changed to avoid MANPADs threat. Currently Russians, cannot fly high altitude due to risk from Ukrainian AD systems. Terrain of Ukraine is flat. Leaving it vulnerable due early detection, missiles. As there is no natural covers like mountains. Not to forget that US, NATO provides actively intelligence to Ukraine. Flying low, fast becomes the only option. As Russian SEAD/DEAD have been ineffective and technological limitations of Russian systems, capability of personnel etc. No targeting pods, precision guided missiles to engage from safe distances.
Coming back to MANPADs, next generation missiles like Sungur with updated capabilities, going to have very high pK rate. Very difficult to avoid at its given range unless there is hard kill system. Going to be popular choice for NATO countries for fast capability boost along with MANPAD launching platforms with fancy EO/IIR sensors.
