Expected time to transfer number?

Hi all
I ported my number today from VOXI.my VOXI SIM disconnected at about half 6 this morning but my old number isn't yet working with my Lebara SIM and I get an error when trying to open the app
when can I expect my old number to be working on my Lebara SIM?
Thanks

Came through at about 3pm but had to clear the storage on the Lebara app to get it to work
