Toilet issue

Hi all!
I'm having some problems with teaching Ria to go outside for a toilet. When she came to our home she was only 8 weeks old and not yet vaccinated so she started using balcony as a toilet. She learned that in a few days and everything was fine. Now, she simply refuses to do anything outside. It doesn't matter how long we wait she always holds until we come home and runs to the balcony I don't see this as a problem yet, she's only 3 months old but i would appreciate any advice to speed up the process of changing the toilet place . Thanks in advance!

Try a drink of water before you take her out , if she does one give her a treat with lots of praise, try to keep her out longer as well till she does a wee ,good luck keep us posted thanks .

Take her out after eating, playing or sleeping and wait until she goes and than give lots of praise.

Also, first thing in the morning don't let her go on the balcony - take her straight out for a walk so she's bursting to go for a pee/poo! Then just stay out until she does something.

Thanks everyone for advices! This morning was very successful. Usually i leave the balcony door opened during the night and she can pee/poo whenever she wants. I didn't think that she could hold during the whole night, but last night i closed the door and this morning i found her waiting in front of the balcony door so i took her out and she did all her peeing/pooing outside. Once again she showed me that i was the problem and not her
