I imported my latest trades in a transactional portfolio, saved it and now the portfolio is broken with the following message:

"We cannot calculate this portfolio as it contains unknown symbols. Some of this portfolio's assets were probably delisted, acquired, or went bankrupt."

It is entirely unhelpful to now know which symbol is causing this.

Never mind, found them in the positions list in red, had to scroll down.

I am missing CH1110760852 from the database.

Also, the import from CSV feature really needs a manual cleanup step where unknown symbols are resolved.
