In fact, mining in Minecraft Mobile is no different from the PC version. In order to mine lava blocks in Minecraft, you will need to craft a bucket. The bucket is made from iron ingots, iron in turn can be smelted from iron ore. Iron ore and lava are mined most often underground or inside a mountain.
I recently discovered such a feature that not all lava can be collected. If it has spilled over the surface, you will not be able to get it, sometimes it is not even visible that it flows from somewhere. But in my case, it is clearly visible that it pours from the block I have extracted
During the excavations, I found another lava and was able to pour it into a bucket calmly
Therefore, do not be upset if you have not managed to get it somewhere, just find another source of lava.
