Recent updates terrible

The last two updates have been terrible. On wi-fi the app doesn’t update or show new notifications when I click on the icon. It also doesn’t show comments or likes on posts while on wi-fi. Switching off wi-fi isn’t much better, particularly tonight. Posts take forever to load and the feed won’t update to most recent. I have an iPhone but other family members have android phones and the problem is the same. FIX this, please!
