I just updated my 7 ultra watch to One UI8 and it has blocked my use of the SHM MOD app that allows me to use it to measure blood pressure. As an FYI to Samsung, this is the main reason I have the watch and won't be upgrading/buying the 8 Ultra watch unless this block is removed, or the application can in some way function for that purpose. I understand that "officially" the BP function is not supported in the U.S. by Samsung b/c of FDA approval status (still not clear on why this is still not possible), but blocking the workaround so many of us use isn't the answer. If you need to block the method the SHM MOD app uses to to allow the BP function, I get that too, but find some way to whitelist this app so it can continue to service a need that many people depend on. You removed the major benefit of the device for a huge number of people. Now I have to see if I can downgrade my current watch to Wear OS 7 somehow and make it useful again, otherwise I'll have to go purchase a device that serves my need and just dump Samsung watches altogether. I know it is unlikely this gets forwarded to the person/people that make decisions, but thought I would try.
