Fix messages not showing up – GroupMe Review

I have used this app for 8 years and in the last month or so, messages will not show up. Then when I send a message, the 30 messages that didn’t show up will pop up and my message makes no sense. Other members of my group are also having this problem. This has NEVER been a problem in the past and is making the app nearly unusable.
