Thank you both for responding so quickly. I would answer your questions, but I think I figured out tbe problem (and it would go along with me not thinking the issue was with the keyboard apps). I narrowed down the issue to only happen using the YouTube app (because this app is where i do most of my typing, and this issue does not happen on Facebook, general online text fields, etc). About 3-4 months ago, YouTube updated their input/ comment text field to include a little icon that will enter a linked time code of the current video play head so others could instantly be directed to that time in the video. That update caused a conflict with the keyboards to where the keyboards would freeze up to 10 seconds before receiving any input. I have only used the default Samsung keyboard and Gboard and these issues appear on both keyboards. Also, when trying to edit a previous comment, you are immediately presented with 'keep writing or discard' and the only way to edit the text is to choose 'discard'. These issues are noticed by many, many users as the YouTube forums are flooded with complaints. I believe my issue is just newly discovered (at least what i have found). Of course, there is zero response from YouTube, but there are reoorted temp fixes out there that require a rollback of YouTube updates and installing an old update (which i do not want to go through).
So, I believe I answered my own question, and tbe answer is that YouTube (once again) doesn't have a very good developer response.
Thanks again for the suggestions.
