Did they over react to the pandemic, yes. From what I see now, probably pretty safe as long as you don't have as note some colorful history or a background that might cause them to detain you, if you do you are SOL.
My son is there again first time since the pandemic for three weeks. He also used to travel monthly there before the pandemic.
