Who I have the same questioned this topic

When doing a voice to text, only the first letter of the first sentence will capitalize.   After subsequent sentences, when I say "period," the next sentence is not capitalized!! This has been going on for about a week.    I have made no changes to language and input.  It still says, English, and Google voice typing.  I use voice typing text a lot...this is a major feature I use...now I can't send texts without the first word being capitalized!  It is not professional.  I have tried clearing caches, etc.  Is this due to some kind of update?  WTF???
