“I’ve been using Upwork for quite some time, having spent over $10,000 on developers and projects, but my experience has gone downhill fast. The app is extremely buggy — I ran into a major billing issue where I had no outstanding payments, yet I couldn’t take on new projects either as a freelancer or a client. I reached out to support, but no one ever got back to me. The chatbot powered by AI just…”Upwork
“The app has several usability issues that significantly impact the user experience. First, copying messages is unreliable. Many times, when I long-press a message and select “Copy,” nothing gets copied. Repeating the action multiple times doesn’t help, and the only workaround is to completely close and reopen the app. Second, the search functionality is limited. When searching for a person or keyw…”Meta Business Suite
“So I have been using this app for the last few months for the company I work for. I have found it somewhat user-friendly and on the other half it’s not.. I need to be able to have dark mode because the white gives me migraines. And it’s just harsh on your eyes. Next, I still have not been able to get our caller ID to pop our company name they chose to work on one issue and not both or follow up on…”Housecall Pro: Field Service
“I rarely write app reviews, but this got so annoying I decided to rate the app. Every time you click on a copart link, you are forwarded to the app’s sign in screen. If you don’t sign in, the app ignores the link content and goes to the search page. And if you do have the app installed it takes over every time you click a copart link, thus you cant use the web view anymore. It’s shameful how ju…”Copart - Online Auto Auctions
“I have this actual application, and then I have the branded app for my marketing company and I have to have both of them on my phone because one or the other has bugs in it that don’t notify me when I’m getting my client messages. It’s either that or I can’t access all of the information that my clients are putting in on their Lead form. As someone else has said as well it doesn’t allow me to full…”HighLevel
“I’ve spent about 12 hours trying to work out the bugs, I’ve integrated high level with my site and it is not giving me notifications to the app anymore, any many times whatever email through the contact form gets totally lost, not in junk or spam folder, it just never gets sent half the time. You have to go through two different sections to access the messaging and emails that do end up showing up…”HighLevel
“I looked past the negative reviews and started to love the app. New update now requires users who are agency admins to only view the app with the “new experience” toggled on permanently. I swear, GHL hires some extremely stupid product managers who don’t understand customer needs. Only going to continue using because the product is necessary for running an agency. But man, their product team needs…”HighLevel
