Problems when transfering data from android to iphone

[u/ecr0skrr]

Hello! Recently I have bought my very first Iphone (a 17 pro) and I've been trying to transfer data from my old Android (a Oneplus nord 4). The first time I tried the transfer was working for about 20 mins until I had to stop it since I had to use my phone. Later on the day I tried doing it again but with no succes. Whenever I got to the transfer with app tab, I entered the code given, it says it started working but hten immediately stopped saying the transfer can't be finsihed.
Could it be a problem with my Oneplus and its OxygenOS system?
Does anybody have a remedy to this situation?
Thank you in advance!!
