Some blocks wont run unless my web browser is in the right page

Greetings thunkable community, whennever i launch my app with my block-heavy page open (in my web browser), everything runs fine but if I’m on other pages, some code won’t run at all.

example :
my_page_2 contains many blocks, i’m currenty editing it and I test the app: it works fine

if I edit my_page_1 instead (whitout changing anything) and test the app : when I navigate to my_page_2 (on android) some blocks will run, some wont. Sometime the database querries won’t launch, sometime buttons won’t execute their function.

Is there some block limit per page or some memory limit I might be crossing ?
