From the Robinhood website:
Changes due to ongoing market volatility

Opening new positions in the securities listed in the table below is currently allowed, but limited. For more context about the decision to limit these securities, read our blog post.

Are there limits to increasing my existing positions?
Yes. The table below shows the maximum number of shares and options contracts to which you can increase your positions. Please note that these are aggregate limits for each security and not per-order limits, and include shares and options contracts that you already hold. These limits may be subject to change throughout the day.

They go on to list around 35 stock that you are limited to buying 1 (yes ONE SHARE) of.
