Minecraft Pocket Edition wont Update

So, I am having issues getting my Minecraft Pocket Edition to update. Its still on 1.16.220. I have  tried the following; I Made sure the Auto updating feature was on. and making sure the tablet was not powered all the way off, I waited three days. I deleted the game and reinstalling it. I also waited about four days.
I would like it if you wrote me back any troubleshooting methods.

Sincerely,
Nathan Jones
