Compensation Eligibility Help

On December 14, 2023, I had three flights scheduled: from Riga to Copenhagen with airBaltic, followed by connections from Copenhagen to Reykjavik and Reykjavik to Boston with Play Airlines. Unfortunately, the Play Airlines flights were canceled due to a strike in Iceland. Despite the strike affecting only the Play Airlines flights, they only provided me with a rescheduled flight two days later on the 16th.

My question is: since Play Airlines did not offer me an alternative flight on the 15th when there was no strike, do I qualify for compensation? I was stranded in the airport for two nights as a result.
