Proofs Very Slow to Open

Over the last couple of days, proofs that I have been trying to access have been slow to open, and when they do open, a page may not load or be missing from view. My proofs are PDFs and are around 1MB to 2MB each. It is hampering my ability to quickly review my documents in a timely manner. I have reached out to Support but was wondering if anyone else has been encountering this issue lately?
