Conversations involving multiple participants, allowing collaboration and information sharing in Teams
We had a ticket opened with Microsoft regarding this issue. They have not confirmed the issue or provided a solution. Instead, Microsoft Support have mentioned that the paste limit is 250k characters in Teams, but it is clear that the new and classic Teams apps process pasted tables differently. They opened internal ticket regarding this issue, but unfortunately it was rejected by the Product group. However, they also opened a community request to improve pasting limits in Microsoft Teams:

Let's make pasting limit in Microsoft Teams great again! Every single vote matters! =)
