iPhone Messages App is freezing while typing a message
It is a time lag as the text shows up a few seconds (or many more) later. Similarly, if I delete text, the text gets deleted after a time lag. If I keep pressing keys out of frustration, it takes longer as now the poor app has more processing to do.
Rebooting my iPhone sometimes helps temporarily. A lack of storage is not causing the problem; I have over 50 GB available in iCloud storage and over 150 GB available on my iPhone.
