Hello @pkWinCity ,
It is still possible, as I was able to do it without issue in both the older 3GE builder and the newer CPE builder:


This was done without requiring a layout block or anything else first, just dragging and dropping the Read More blocks in side-by-side. I was also able to add other block types between two of the same type in both browsers, as shown below.

As an initial troubleshooting step you can do from your end, try adding a Read More block fully on its own at the bottom of your email by double-clicking the block option in the left-hand menu. Then, drag over the other two blocks that will be in that row and drop them to the side of the bottom one. Then simply use the row's directional icon to drag it up to where you need it.

If you continue to have issues using a regular email builder (3GE or CPE), I'd recommend some basic connectivity troubleshooting. Please keep in mind that when I say connectivity, I'm not necessarily referring to just your internet speed. There are a number of elements that can affect website connectivity and accessibility on an individual basis.
The most common culprits are typically incompatible browser extensions, problematic caching or cookies that need to be cleared, or interference from an ad/pop-up blocker, VPN, or other security software erroneously trying to block elements from our site from functioning as intended. Temporarily disabling these tools, and then refreshing our site can help narrow down the source of the issues. Testing to see if the issue occurs on other browsers, in Incognito/Private mode, on other devices, or even other networks can also help narrow down the source of the problem.
Other potential issues could be excessively long campaigns, which result in increasingly more bandwidth being utilized to show the email and maintain autosaving. Too much, and it can cause severe lag or outright crashes, depending on your browser, internet provider, or device. Sometimes resetting your internet router, whether you're using wifi or ethernet, can alleviate such issues as well. Just like phones, computers, and TVs, even routers need the occasional reset or power off to run smoothly.
If none of those alleviate the issues, please call our general support number so they can continue troubleshooting with you live. If possible, please have a screenshot of your speed test, including the More Info section, ready for the phone agent.

If you're trying to build an email using the custom code editor, or an integrated editing system of some kind, then that isn't something we're going to be able to troubleshoot for you. For custom code emails, please call our general support and request to speak with the Tier 2 custom code team. If using an outside / integrated editor, we'd recommend reaching out to their support.
