Hello @Saad_Awan,
I completely understand your point. As it stands now, though, using multiple API tokens in the same React app runtime will not work. It could, but the SDK will need to be updated. So, for now, the best option is to use a single resource for all of them. However, we have created a story to investigate this further because it makes sense to make it possible.
If you do not wish to wait, then there is the option to implement this functionality yourself, as Transifex Native wasa developed as an open source project so that more people can contribute or expand the solution. We have also setup a Native specifications document as a blueprint for building a Transifex Native SDK on new frameworks.
Does this help? I also want to thank you for bringing this to our attention, as it does make sense.
Regards,
Ryan
