I used PayPal for years, but lately itโs been one of the most frustrating payment services Iโve dealt with. Their customer support feels almost nonexistent โ long wait times, scripted replies that donโt solve anything, and nobody seems empowered to actually help you.
One of the worst things is how easily they freeze or limit accounts, sometimes without clear explanation, leaving you unable to access your money for weeks. And when you try to dispute a charge or problem with an order, it often feels like you get brushed off rather than any real help.
Overall, PayPal used to be convenient, but recent experiences on safety holds, opaque policies, and unhelpful support make it feel more like a headache than a reliable way to pay or get paid
I like PayPal, it has a high security standard. Except when I am the one suffering a chargeback for some flimsy reasons.

I'm 18M Indian. Growing up I've always been a daydreamer, if you may. Since 8th grade - I'm fascinated by programming. And I'm good at it too. But I'm not cocky too. I wouldn't say I'm at an advanced level, but I can most probably solve any problem - in time - with my skills. I also keep my skills brushed by solving problems on Hacker Rank (every day or alternate days) and try my best to contribute on... Source: almost 3 years ago
(I live in USA) When I go to payments under my shopify account to add paypal as a payment method I am having trouble doing so. I first click activate paypal > activate paypal express checkout which directs me to a "security challenge" (confirm I am not a robot). Then it just brings me to paypals website (paypal.com/us/home). When I sign in nothing happens, I am just on my paypal homescreen. Source: over 3 years ago
