We've moved it to this help board as it fits its content better.
What you mention is an expected behavior for Chrome browsers, which is called "tab freezing". When you collapse a Tab Group, Chrome will automatically freeze those tabs in order to free up system resources like RAM to be available for other system functions. When you expand the Tab Group again, those tabs will be ready for you to continue using them.
Due to this, we suggest you keep using the Web Player as a normal tab and not as a part of a group, which leads to this issue.
Let us know if you have any questions.
