Lol. is that a reference to the Sally Ride flight that terminated early?

Boeing's Starliner can stay in space beyond 45-day limit, NASA saysQuote: Starliner, in fact, is rated to stay as long as 210 days on orbit once operational missions begin, he pointed out. But, as this is only Starliner's third mission in space, and its first with astronauts, NASA had been unsure about the battery performance in orbit before now.
When Space.com asked how long the mission could continue, Stich said, "We haven't decided how long to extend it yet." Starliner has 12 different batteries, he explained. Before this flight, similar batteries sat on the ground for a year and were then tested to make sure there were no defects, and none were found. So it's a battery issue?

I thought at one point the time limit (45 days?) was related to helium levels required to operate the engines. I don't know if that timeframe was based on the measured leakage or something else. Helium it notoriously difficult to keep contained.

Also used a lot of bubble soap on propellant systems.

I guess it was. We used Heckerman type III leak check compound and pressurized the systems with helium.

ASA says it is “evaluating all options” for the safe return of Starliner crewQuote: One informed source said it was greater than a 50-50 chance that the crew would come back on Dragon. Another source said it was significantly more likely than not they would. To be clear, NASA has not made a final decision. This probably will not happen until at least next week. It is likely that Jim Free, NASA's associate administrator, will make the call. I read somewhere that the space station is running low on food.
