We have no solutions
We suspect this might be a bug with CFNetwork, as we did not encounter this issue on older iOS versions. We hope for a swift resolution as this issue is impacting a large number of our users. We are more than willing to provide any additional information needed or try any potential solutions. Thank you!"
