Don't recieve all mails

Hi
I have the issue that some mails are not recieved. Ive tried to change password on LinkedIn and didn’t recieve the mails they should send. Went to my webmail page and there they were! At the same time I recieved other mails. What happends?

Do you have Categories option turned on, your emails may be in a different category?
Try turning Categories off:
*Settings > Mail > Categories then untick “Show categories”
Then click Apply or Save & Close
See if that resolves the issue.
