my wife, son and I all have iPhone 10 xr's. all are up to date. all of a sudden, if one of us tries to send a video that we took, the recipient receives a video that is tiny and pixilated. what gives? not every time, but most of the time.
yes, iMessage, just like we have been for the last 10 years. I haven't changed a thing as to how we do this...unless un update took it upon itself to change something? Videos could be anywhere from two seconds to two minutes. same result.
In my case the (Verizon) signal is always very strong. What's more is that it also happens when we're in our house using wifi which also has a strong signal.
