It's not that I do not want to "address" it, as you said it only affects some users.
I cannot replicate it on my side with a 4 year old android phone, I do believe it is because phones have issues loading the map itself which is very high resolution (8K) but that is for obvious reasons to be able to zoom in, amongst other features.
I could however after the game is complete do a lightweight version which would involve going hand by hand to all scenes with the map and adjust to a smaller resolution version.
Sorry for any inconvenience that this might cause, I intend to address this at the very late stages of the game.
(Which should be next year)
