Forms no longer working for IPhone users

have had the service since 2019, no issues. 2 weeks ago all of my forms quit working for IPhone users and really lag for Android users. For IPhone users just the header appears, but the form never loads. I have been submitting tickets and emails for 2 weeks to support but no reply. I did get one email from [email protected] with just a preview of an email I sent. Did they go out of business or sell to 123formbuider.com as they have the same address. We pay for this service, we are a charity and just had our big donation drive and lost a lot of donors because of the form not working.
