just lost out on a property

hi i’m apartment hunting in sydney at the moment and was wondering if this is normal?

i saw an apartment on wednesday night (private inspection) and i was interested - i asked for the contract & bought the strata report.

i told the REA that i was interested and would be sending these documents to my solicitor. i also told her that i wanted to see the apartment again in the daytime (at the saturday inspection) to see how much natural sunlight it’ll get.

i just got a notification saying that the property is under offer :/ she didn’t even call me to check if i wanted to offer. i feel quite defeated.

is it normal for an REA to not check if an interested party would offer/beat another offer? should i have just offered before the saturday inspection?

thanks!
