First, I'd like to thank the PF management for your delivery of a superior scientific discussion forum. But I've got a request that might be logistically impossible for you, or simply too difficult to even bother trying. I typically access PF via my iPhone, and there often seems to be issues with translating many mathematical expressions to this format, resulting in my seeing only symbolic gibberish that means nothing to me. This effectively reduces my understanding of it from little to none. Is this an iOS compatibility issue on your side that might be addressed at some point, or can I fix this on my side by downloading some type of a mathematical font app? Thank you again.
