Tacx Neo 2T power balance - BT and 3rd party apps

I am planning to buy a Tacx Neo 2T and wanted some information on power balance. So far, with another trainer, I have been riding the Rouvy app using the iPad 9th gen. I know that the power balance support was added in the Tacx Neo 2T update. However, I read somewhere that this data is only transmitted via ANT+, not via BT. Is it true? Unfortunately, the iPad does not support ANT+, so I will have to use BT. So I have two questions.
1. Is power balance data sent via BT as well?
2. Is the power balance data supported only by garmin devices (e.g. Edge) and Tacx Training, or also by other apps, e.g. Rouvy?
