I’m not going to blame this product alone b/c I bought protective accessories that were designed for it that DON’T FIT.  Is this in a non-standard Lenovo replacement case?  Is it not really a 300e?  We may never know because there are too many pieces in play but the Gumdrop case is too small and the screen protector is too big.  So far I’ve wasted a lot of money on this purchase and I don’t even have it set up yet.  AND I’m not a newbie b/c I worked on Chromebooks for 10 years before I retired and this is why I use Apple for my personal use.  Good grief, it shouldn’t be this hard.
