Because micro-sd in power-on work on RB433AH, and it does not work (micro-sd) after reboot? compatibility?

i'm sorry, your question is not clear. please rephrase?

sorry!
after reboot micro-sd is not working

it works fine for us and for everyone else. what do you mean by "not working"? it doesn't appear in STORE menu? did you try to upgrade RouterOS and RouterBOOT? Did you change the card brand?

brands compatible?
