Yes! I have had this issue for ages on macrumors since the last major overhaul, and a couple other forums that use the same software.
when typing on a forum, it won’t auto capitalize words, or autocorrect many misspellings, and when backspaceing, it’ll behave erratically and double backspacing spaces when erasing whole words. It’s hard to describe. It’s been a frustrating experience and I’ve largely avoided replying to threads on my iPhone because of it.
im replying using my iPhone, and you can see how the first word of each new paragraph isgnores any autocorrect. (Such as capitalizing “I” and adding the apostrophe to “I’m.”
im running iOS 15, using Safari… but this has happened on iOS 14, 13… as long as this latest major forum overhaul has been in existence. Happens on iPad and iPhone.
I think Tonymacx86 has the same issue, as it runs the same forum software. Something like TurboBricks does not, as they’re still running the older BB forum software.
