Hi, Footrot. From here, we'd advise making sure you're updated to the latest iPadOS version as shown here: Update your iPhone, iPad, or iPod touch

Once fully updated, if you continue to notice this issue, we'd recommend reaching out to Apple directly to look into this with you further: Get Support

Cheers.
