The hardware of those MyQ gargae door openers are fine. However the MyQ cloud implementation have been breaking so many times over the years, with the company (Chamberlain) abandoning and changing stuff, left and right, all the time.
So Chamberlain’s reputation isn’t there, at all.
Longer term, I would even venture to say that there is no fix to the MyQ cloud (echoing to David’s “No, not really.” comments above). Your best option is to bite the bullet and put together your own non-cloud alternatives. There are a couple of ways to do it, and in general Ratgdo mentioned above is a solid choice.
The second best option is to wait for Chamberlain to improve. (But I would not hold my breath.)
