I don't see anything to be worried here at all. But if you will start applying all scenarios on 'your' application, then you'll be worried only.
There is nothing in our hands (except following CIC's next steps), and I will suggest you all to go with the flow. For instance, earlier, there were no communication from IRCC side. Then, gradually, they started sending out 3/4 pointer emails. Then, we noticed ALs too. Now, people have started receiving re-medicals also. Moreover, there is too much noise on social medial platforms also.
Considering all these updates (I know CIC is super slow in handling COPR expired cases), you all should remain positive still. Remember that, CIC is still working on COPR expired cases. We all know they should have dealt with such cases in a better way, there is a lack of process refinement for sure. But, we all should also understand they're not cancelling your COPRs or PR visas, so cheer up!
Look at the positives and be motivated by all these updates. Stay strong!
