How can I fix low memory error message

I have been playing a uefn game on my phone called realistic family rp and every time I try to enjoy the game I get the low memory error message and then it kicks me out the server unexpectedly and when I arrive to lobby it says island memory has reached its max, I tried submitting bug reports but after about a week I’m still experiencing the bug , so I emailed epic games via help website and they said it may be my internet or the phone it’s self but I tested the theory but this was not the case and I have noticed that I get the message faster when I go through a rift a few times, I think the error message came from the large amount of updates that added a lot of new things that I think may have caused the island memory to become unstable, i don’t know how to contact the creator who’s name is caymass to let them know about the issue.
