Restoration of Pro version in new mobile for "Body measurements" app

Hello. I just changed mobile phone and I am trying to restore the pro version I bought today to my new mobile but this doesn’t seem possible. It asks me to pay again. Can you help me how I can do it? Apparently, I want to fully transfer the profile from the old mobile to the new one and also the Pro version without ads.
Thanks in advance!

Hi.
You need to use the same Google account on new device.
Please mail me so that I could check your purchase state.
