I'm sorry to hear that you're experiencing a login issue with your Webflow account linked to Google. I can provide some general advice and possible reasons behind this issue.
1. Double-check your login credentials: Firstly, ensure that you are entering the correct login credentials for your Webflow account. If you're unsure, try resetting your password by clicking on the "Forgot password" link on the login page.
2. Clear cache and cookies: You mentioned that you have already tried this, but it's worth mentioning again. Clearing cache and cookies can potentially resolve login issues caused by stored outdated data. However, since you've already attempted this, let's move on to other possible solutions.
3. Manually disable browser extensions: Some browser extensions, particularly those related to privacy and security, can interfere with the login process. Temporarily disable any installed extensions and try logging in again. If successful, re-enable extensions one by one to identify the problematic one.
4. Try using a different browser or device: Sometimes, login issues can be browser-specific. Try accessing your Webflow account using a different browser or device. This will help determine if the problem is isolated to a particular browser or device.
5. Check your Google account permissions: Verify that Webflow has the necessary permissions to access your Google account. Go to your Google account settings and review the connected apps and websites. If you find Webflow listed, ensure that it has the appropriate access permissions enabled.
6. Network-related issues: Occasionally, network issues can interfere with logging in. Try connecting to a different network, such as a mobile data network or a different Wi-Fi network, to see if that resolves the problem. This step will help identify if the issue is related to your network.
7. Reach out to Webflow support again: You mentioned that you've already contacted Webflow support, but they have been unresponsive for four days. It's possible that they are experiencing a high volume of inquiries or technical difficulties. It may be worth reaching out to them again, providing all the details and steps you have taken to troubleshoot the issue.
8. Temporary solution for portfolio deadline: If you have an urgent need to submit your portfolio for a bootcamp, consider creating a temporary portfolio using alternative platforms like Behance, Dribbble, or even a personal website. This will allow you to meet the deadline while you continue working on resolving the login issue with Webflow.
Remember, my response is not specific to 2021, but these are general suggestions to help you troubleshoot and potentially resolve the login issue with your Webflow account. Good luck, and I hope you're able to access your account soon.
